  • Fit and compression levels vary, influencing mobility and moisture management during skiing.
  • Price ranges significantly impact material quality, durability, and performance features.

More Details on Our Top Picks

  1. Runhit Men’s Thermal Underwear Set Fleece-Lined Long Johns for Cold Weather

    Runhit Men's Thermal Underwear Set Fleece-Lined Long Johns for Cold Weather

    Best Overall for Versatile Cold Weather Use

    View on Amazon

    This fleece-lined set stands out for its excellent warmth and flexibility, thanks to a stretchy polyester-spandex blend that wicks moisture effectively. Compared with the heavy-duty options like the Cuddl Duds set, it offers better mobility, making it suitable for active outdoor pursuits. However, its warmth can be excessive for milder conditions, and limited color choices may not appeal to everyone. Its fleece lining provides superior insulation, while the moisture-wicking fabric ensures comfort during high-intensity skiing. The main tradeoff is that it’s best suited for very cold days; on milder days, it might feel too warm and bulky.

    Pros:
    • Fleece-lined for superior warmth in extreme cold
    • Stretchy fabric allows unrestricted movement
    • Moisture-wicking and breathable for comfort
    Cons:
    • May be too warm for mild winter days
    • Limited color options reduce style variety

    Best for: Active skiers or outdoor enthusiasts who need reliable warmth without sacrificing mobility in very cold weather.

    Not ideal for: Casual users or those skiing in mild winter conditions who may find it too warm or bulky.

    • Fabric composition:88% Polyester, 12% Spandex
    • Care instructions:Machine Wash
    • Origin:Imported
    Our verdict
    “This set is perfect for those facing very cold conditions who need both warmth and flexibility.”
  2. Cuddl Duds Heavyweight 2-Piece Thermal Base Layer Set for Women

    Cuddl Duds Heavyweight 2-Piece Thermal Base Layer Set for Women

    Best for Maximum Warmth and Layering Flexibility

    View on Amazon

    This heavyweight set is designed for the coldest days, with a fleece-lined interior that outperforms lighter options like Ekouaer in insulation. It provides a sleek fit and features like thumbholes and UV protection, making it ideal for layering or lounging in extreme cold. While its warmth is unmatched, it may be too heavy and warm for less severe conditions, and potential pilling over time could affect its appearance and longevity. Compared to the Ekouaer set, it offers a more substantial feel, but at the expense of some breathability and flexibility.

    Pros:
    • Fleece-lined for exceptional cold-weather insulation
    • Flexible design allows easy movement
    • Features like thumbholes and UV protection add versatility
    Cons:
    • Potential for pilling with frequent use
    • Too warm for mild winter conditions

    Best for: Women who ski or spend time outdoors in the most frigid weather and need a highly insulated layer.

    Not ideal for: Warm-weather skiers or those who prefer lightweight, less bulky thermal underwear.

    • Fabric Composition:93% Polyester, 7% Spandex
    • Fabric Weight:235 GSM
    • Features:Fleece-lined, moisture-wicking, breathable, thumbholes
    Our verdict
    “This set is ideal for women facing extreme cold who prioritize maximum insulation and comfort.”
  3. Ekouaer Thermal Underwear for Women Long Johns Base Layer Winter Clothes

    Ekouaer Thermal Underwear for Women Long Johns Base Layer Winter Clothes

    Best for Snug Fit and Modern Features

    View on Amazon

    This set offers a snug, modern fit with a fleece-lined interior that retains body heat effectively. Its 90% polyester and 10% spandex fabric provides excellent stretch for comfort, similar to the Cuddl Duds but with a more tailored, flattering silhouette. Features like thumbholes and a modern-rise waistband enhance functionality, yet the care instructions—requiring drip drying and no bleach—may be inconvenient for busy skiers. While it excels in warmth retention, the lack of detailed size options might make sizing a challenge for some buyers.

    Pros:
    • Warm fleece-lined interior retains body heat
    • Stretchy fabric offers natural movement
    • Functional thumbholes and modern-rise waistband
    Cons:
    • Care instructions require gentle handling
    • Limited size or fit details may affect perfect sizing

    Best for: Women who want a form-fitting, stylish thermal base layer for winter activities and value comfort and stretch.

    Not ideal for: Those who prefer easy-care options or need a looser fit for layering in extreme cold.

    • Fabric composition:90% Polyester, 10% Spandex
    • Fabric weight:210 GSM
    • Design features:4-way stretch, thumbholes, modern-rise waistband
    Our verdict
    “This pick suits women seeking a snug, stylish thermal layer with excellent stretch and warmth.”
  4. Men’s Thermal Underwear Long Johns Set for Cold Weather Hunting Base Layer

    Men's Thermal Underwear Long Johns Set for Cold Weather Hunting Base Layer

    Best for Maximum Warmth and Breathability in Extreme Cold

    View on Amazon

    This men’s set emphasizes warmth and breathability, with a midweight 220g/m² fleece interior that outperforms lighter options like the Ekouaer in extreme cold. Its soft, moisture-wicking fabric reduces pilling and shrinkage, making it durable for outdoor pursuits like hunting or skiing in severe conditions. While it offers various thickness and style options, the limited info on long-term durability and specific sizing might be a concern for dedicated outdoor users. Compared to lightweight options, it provides robust insulation but may feel bulky for active skiing.

    Pros:
    • Excellent warmth and lightweight feel
    • Moisture-wicking fabric reduces pilling and shrinkage
    • Multiple style and thickness options
    Cons:
    • Limited durability information over time
    • No detailed sizing info provided

    Best for: Men engaging in extended outdoor activities or skiing in severe cold where maximum insulation is critical.

    Not ideal for: Casual skiers or those in moderately cold weather who prefer lighter, less bulky thermal underwear.

    • Fabric:90% polyester, 10% spandex
    • Weight:Midweight (220g/m²)
    • Care instructions:Machine wash
    Our verdict
    “This set is tailored for men facing extreme cold and seeking reliable warmth with breathability.”
  5. SIMIYA Thermal Underwear Set for Women Long Johns Fleece Lined Base Layer

    SIMIYA Thermal Underwear Set for Women Long Johns Fleece Lined Base Layer

    Best for Comfort and Flexibility in Cold Weather

    View on Amazon

    This fleece-lined set combines warmth with flexibility, thanks to a 95% polyester and 5% elastane blend that provides a snug yet comfortable fit. It features a tagless design and moisture-wicking fabric, making it suitable for outdoor activities or everyday winter wear. While it excels in comfort and durability, some buyers might find it too snug, especially if they prefer looser layers. Limited color options and size details could also be a drawback for those seeking more variety or precise fit guidance. Compared with heavier sets like Cuddl Duds, it offers a lighter feel while maintaining warmth.

    Pros:
    • Warm fleece-lined interior for cold weather
    • Soft, moisture-wicking, and comfortable fabric
    • Flexible 4-way stretch for natural movement
    Cons:
    • May be too snug for some preferences
    • Limited color options and sizes

    Best for: Women who want a comfortable, flexible thermal layer for outdoor sports or daily winter wear.

    Not ideal for: Those who prefer looser fits or need a broader range of sizes and colors for different preferences.

    • Fabric type:95% Polyester, 5% Elastane
    • Care instructions:Machine Wash
    • Features:Fleece lining, 4-way stretch, moisture-wicking
    Our verdict
    “This set is ideal for women prioritizing comfort and flexibility in their thermal wear for winter activities.”
  6. Thermal Underwear for Women Long Johns Base Layer Pajama Sets for Cold Weather

    Thermal Underwear for Women Long Johns Base Layer Pajama Sets for Cold Weather

    Best Overall for Women’s Cold Weather Comfort

    View on Amazon

    This fleece-lined set stands out for its combination of warmth and flexibility, making it ideal for women engaging in winter activities like skiing or hiking. Unlike the fleece-lined options for men, it offers a snug fit that feels lightweight yet warm, thanks to the polyester-spandex blend. Its moisture-wicking properties help keep you dry during active pursuits, and the four-way stretch ensures freedom of movement. The main tradeoff is its snug fit, which could feel constrictive if the size isn’t chosen carefully, and limited color options may not suit everyone’s style. Compared to fleece-lined men’s options like the Runhit set, this provides better tailored fit and moisture management for women, but may be less versatile for lounging in very relaxed fits. This pick makes the most sense for active women who need high performance without bulk, especially in cold conditions.

    Pros:
    • Fleece-lined for exceptional warmth and comfort
    • Moisture-wicking and quick-drying for active use
    • Four-way stretch provides excellent mobility
    Cons:
    • May feel tight if size is not selected correctly
    • Limited color options reduce customization

    Best for: Women seeking a warm, flexible layer for skiing, hiking, or outdoor winter sports

    Not ideal for: Women who prefer loose-fitting thermal wear or more color choices for casual lounging

    • Fabric:87% Polyester, 13% Spandex
    • Care instructions:Machine Wash
    • Origin:Imported
    Our verdict
    “This set is a top choice for active women who prioritize warmth and flexibility in cold weather.”
  7. Runhit Men’s Thermal Underwear Set Fleece Lined Long Johns for Cold Weather

    Runhit Men's Thermal Underwear Set Fleece Lined Long Johns for Cold Weather

    Best for Men Needing Versatile Warmth

    View on Amazon

    This fleece-lined set is designed to excel in providing warmth and flexibility during outdoor winter pursuits, making it a solid choice for active men. Compared to the Amazon Essentials set with its waffle knit fabric, the fleece lining here offers superior insulation, especially in very cold climates. Its stretchy material caters to dynamic movements, whether you’re skiing or hunting, but potential users should be aware that it might feel bulky for those who prefer a slim profile. The limited color options and lack of detailed sizing info could be drawbacks for some buyers. While the Amazon waffle knit set offers breathability and a snug fit, this fleece-lined version prioritizes maximum warmth and mobility. It’s best suited for men who need dependable thermal protection during vigorous outdoor activities.

    Pros:
    • Fleece lining delivers excellent warmth for cold weather
    • Stretchy fabric ensures ease of movement
    • Moisture-wicking keeps you dry during activity
    Cons:
    • Potentially bulky for some users
    • Limited color options and sizing details

    Best for: Active men looking for a warm, flexible base layer in cold conditions

    Not ideal for: Men who prefer lightweight, less bulky thermal layers or detailed sizing info

    • Fabric composition:88% Polyester, 12% Spandex
    • Care instructions:Machine Wash
    • Origin:Imported
    Our verdict
    “This fleece-lined set is ideal for men demanding maximum warmth and mobility in severe cold conditions.”
  8. Amazon Essentials Men’s Slim Fit Thermal Long Johns Underwear Set, Breathable Waffle Knit for Cold Weather Wear, Multipacks

    Amazon Essentials Men's Slim Fit Thermal Long Johns Underwear Set, Breathable Waffle Knit for Cold Weather Wear, Multipacks

    Best Budget-Friendly Slim Fit for Men

    View on Amazon

    This set offers a slim fit design with breathable waffle knit fabric, making it a practical choice for men who want a tailored look without sacrificing warmth. Compared to fleece-lined options like the Runhit set, the waffle knit provides better breathability, reducing overheating during less intense activities. Its elastic waistband and rib cuffs ensure a snug fit, but the slim profile might not suit those who prefer looser thermal layers or need extra room for layering. The multipack offers good value, though the cotton-poly blend could shrink if not washed carefully. While not as plush as fleece-lined options, this set balances comfort, durability, and affordability for everyday winter wear, especially in milder cold climates.

    Pros:
    • Slim fit offers a tailored, comfortable look
    • Breathable waffle knit fabric prevents overheating
    • Elastic waist and rib cuffs provide a snug fit
    Cons:
    • Limited color options
    • Material may shrink if not washed properly

    Best for: Men seeking a breathable, slim-fit thermal base layer for moderate winter conditions

    Not ideal for: Men who prefer loose-fitting thermal wear or plan to wear it in extreme cold without additional layers

    • Fabric type:60% Cotton, 40% Polyester
    • Care instructions:Machine Wash
    • Bottom style:Long Underwear
    Our verdict
    “This multipack is well-suited for men looking for affordable, breathable thermal wear with a sleek fit.”
  9. Thermal Underwear for Women Long Johns Set Fleece Lined Winter Cold Weather

    Thermal Underwear for Women Long Johns Set Fleece Lined Winter Cold Weather

    Best for Soft, All-Day Warmth

    View on Amazon

    This fleece-lined set offers plush comfort and reliable warmth, making it ideal for women who spend long hours outdoors in winter. Its four-way stretch fabric ensures a flexible, comfortable fit, comparable to the fleece-lined women’s sets like the B0DB81H4N5. The lightweight, moisture-wicking material helps prevent overheating, but it may be too warm for milder winter days or indoor use. Its soft fleece lining delivers a cozy feel, although its limited color options might not appeal to all. While similar in warmth to the Spyder set, this option emphasizes softness and all-day comfort, making it suitable for extended outdoor activity or as a reliable base layer in extreme cold.

    Pros:
    • Super soft fleece lining provides plush comfort
    • Four-way stretch fabric offers excellent flexibility
    • Lightweight and moisture-wicking for all-day wear
    Cons:
    • May be too warm for mild winter days
    • Limited color options

    Best for: Women needing a soft, warm, and flexible layer for prolonged outdoor winter activities

    Not ideal for: Women in mild winter climates or those desiring more color choices for casual wear

    • Fabric:92% Polyester, 8% Spandex
    • Lining:Fleece
    • Care instructions:Machine Wash
    • Origin:Imported
    Our verdict
    “Ideal for women seeking a plush, warm base layer for extended outdoor exposure in very cold weather.”
  10. Spyder Women’s Thermal Underwear Set – 2-Piece Breathable Soft Fleece Lined

    Spyder Women's Thermal Underwear Set - 2-Piece Breathable Soft Fleece Lined

    Best for Layering and Cold Weather Coverage

    View on Amazon

    This fleece-lined set from Spyder offers reliable warmth with a focus on coverage and comfort. Its soft fleece interior provides insulation without bulk, and the full set includes a long-sleeve top and full-length bottoms, making it perfect for layering under ski gear or winter clothing. Compared with other fleece-lined options, such as the B0DB81H4N5 set, Spyder’s design emphasizes full coverage and breathability, which is ideal for milder winter days or when you need a dependable base layer. A potential downside is that it runs large, so sizing down is recommended for a better fit, and the fleece lining may need gentle washing to maintain softness. This set is best suited for women who want reliable warmth with a focus on layering versatility.

    Pros:
    • Soft fleece-lined interior provides warmth without bulk
    • Flexible stretch fabric moves with the body
    • Full coverage enhances warmth during cold days
    Cons:
    • Runs large, so sizing down is necessary
    • Fleece lining requires careful washing to preserve softness

    Best for: Women who need full coverage and reliable insulation for outdoor winter activities or layering under ski gear

    Not ideal for: Women who prefer lightweight, form-fitting layers or are concerned about needing to size down

    • Fabric type:92% Polyester, 8% Spandex
    • Care instructions:Machine Wash
    • Origin:Imported
    • Set includes:Long-sleeve top and full-length bottoms
    Our verdict

  11. Thermal Underwear for Women Long Johns Base Layer Pajama Sets for Cold Weather

    Thermal Underwear for Women Long Johns Base Layer Pajama Sets for Cold Weather

    Best for Cozy All-Day Comfort and Versatility

    View on Amazon

    This women’s thermal set stands out for its fleece lining that offers exceptional warmth and a snug fit, making it perfect for both outdoor winter activities and lounging at home. Compared with the heavier Cuddl Duds Heavyweight 2-Piece Thermal Base Layer Set, it is more flexible and less bulky, though it might feel tight for those with a broader build. The moisture-wicking fabric helps keep skin dry during movement, but the snug fit can be a drawback if you prefer a looser feel or have sizing concerns. Its four-way stretch ensures easy movement, which is essential for skiing or active winter pursuits. Still, the material’s snugness may require careful sizing, especially if layering underneath. Overall, this set is best suited for women who prioritize comfort, flexibility, and moisture management during active cold-weather days.

    Pros:
    • Fleece-lined for warmth and comfort
    • Moisture-wicking and quick-drying
    • Four-way stretch for flexibility and movement
    Cons:
    • Sizing may require careful attention to fit
    • Material may feel snug for some users

    Best for: Women who want a comfortable, flexible base layer for outdoor winter sports or active pursuits without feeling restricted.

    Not ideal for: Women who prefer a looser fit or have larger body frames, as the snug design may feel too tight or sizing may be tricky.

    • Fabric Composition:87% Polyester, 13% Spandex
    • Care Instructions:Machine Wash
    • Origin:Imported
    Our verdict
    “This pick makes the most sense for women seeking a snug, versatile thermal set that handles active winter days well.”
  12. Thermal Underwear for Women Thermal Set Fleece Lined Leggings Long Johns

    Thermal Underwear for Women Thermal Set Fleece Lined Leggings Long Johns

    Best for Durable Warmth and All-Day Comfort

    View on Amazon

    This fleece-lined set excels in providing consistent warmth, making it a great choice for women who spend long hours outdoors or need reliable insulation. Unlike the Thermal Underwear for Women Long Johns Pajama Sets, its high-stretch fabric offers superior mobility, especially during skiing or hiking. The breathable, moisture-wicking tech keeps sweat at bay, reducing chafing and discomfort. However, its thick fleece lining can be too warm for milder winter days or indoor use, which may limit its versatility. Limited color options are a minor inconvenience for some buyers. Overall, this set is ideal for women who prioritize durability, warmth, and comfort in extreme cold or high-intensity winter activities.

    Pros:
    • Fleece-lined for warmth and comfort
    • High stretch fabric for flexible movement
    • Breathable and moisture-wicking technology
    Cons:
    • May be too warm for mild weather
    • Limited color options

    Best for: Women engaging in outdoor winter sports or extended cold-weather outdoor work who need both warmth and durability.

    Not ideal for: Women seeking lightweight or multi-season thermal layers, or those with mild winter climates where heavy fleece may be excessive.

    • Fabric composition:10% Elasthan, 90% Polyester
    • Care instructions:Machine Wash
    • Origin:Imported
    • Features:Fleece-lined, thickened, high stretch, breathable, moisture-wicking
    Our verdict
    “This set is best suited for women needing durable, warm layers for extreme cold or prolonged outdoor activity.”
  13. Cuddl Duds Heavyweight 2-Piece Thermal Base Layer Set for Women

    Cuddl Duds Heavyweight 2-Piece Thermal Base Layer Set for Women

    Best for Maximum Warmth and Winter Layering

    View on Amazon

    This heavyweight thermal set is designed for the coldest days, with a fleece-lined interior that provides plush insulation. Compared with the lighter Thermal Underwear for Women Fleece Lined Leggings, it offers more bulk and warmth, making it ideal for extreme winter conditions or layering under ski gear. Its moisture-wicking fabric keeps sweat away during active pursuits, while the modern fit with thumbholes and a high-rise waistband adds convenience and comfort. However, its heavier weight can be restrictive for some, and the limited color options might not appeal to everyone. This set makes the most sense for women who need serious warmth and are less concerned about bulk or style for indoor use.

    Pros:
    • Warm fleece-lined interior
    • Moisture-wicking and breathable fabric
    • Modern fit with functional details like thumbholes
    Cons:
    • May be too warm or bulky for milder days
    • Limited color options

    Best for: Women facing very cold weather or engaging in outdoor winter sports who need maximum insulation.

    Not ideal for: Women who prefer lightweight, less bulky layers or who are active indoors where heavy insulation isn’t necessary.

    • Fabric Composition:93% Polyester, 7% Spandex
    • Fabric Weight:235 GSM
    • Care Instructions:Machine Wash
    • Origin:Imported

    This men’s fleece-lined set offers a solid balance of warmth and flexibility, comparable to the women’s Heavyweight Thermal Set. Its four-way stretch and moisture-wicking fabric make it suitable for outdoor activities, skiing, or lounging. While it provides excellent insulation, its heavier weight can become uncomfortable in milder conditions, and limited color options might restrict style choices. The inclusion of odor control adds convenience for all-day wear. Compared to lighter options, it focuses on maximum warmth at the expense of some mobility in less cold environments. This pick is perfect for men who want dependable thermal layers for cold days without sacrificing comfort or movement.

    Pros:
    • Fleece lining provides excellent warmth
    • Flexible four-way stretch for mobility
    • Moisture-wicking and odor control for all-day comfort

    • Limited color options

    Best for: Men who need reliable, warm base layers for outdoor winter activities or extended cold exposure.

    Not ideal for: Men seeking lightweight or multi-season thermal wear, or those who prefer a looser fit for indoor use.

    • Care instructions:Machine Wash

Factors to Consider When Choosing Thermal Underwear For Skiing

Choosing the right thermal underwear for skiing involves understanding key factors that influence performance and comfort. The best base layers should keep you warm without overheating, wick moisture efficiently, and fit well under your outer gear. Beyond features, considering how each factor aligns with your skiing style and typical weather conditions will help you make a more informed choice.

Material and Fabric Technology

Look for fabrics that combine wool, polyester, or synthetic blends designed for thermal insulation and moisture-wicking. Fleece lining adds warmth but can add bulk, so consider your layering needs. Advanced fabrics with grid or waffle patterns increase breathability and reduce weight, making them ideal for high-output skiing. Avoid overly thick or non-breathable materials that can cause sweating and discomfort.

Fit and Compression

A snug fit enhances insulation and moisture management by trapping body heat close to the skin. However, too tight can restrict movement or cause discomfort, especially during long ski days. Conversely, loose-fitting options may not insulate as effectively and can bunch up under outer layers. Consider your activity level and personal comfort preferences when choosing between compression and relaxed fits.

Weight and Thickness

The weight of thermal underwear impacts warmth and mobility. Lightweight options excel in milder weather or as a base layer under tight outerwear, while heavyweight sets provide maximum insulation in extreme cold. Think about the typical temperatures you’ll encounter and your layering system; thicker layers might be unnecessary in milder conditions and can limit movement if too bulky.

Durability and Maintenance

Durability depends on fabric quality and construction, especially if you’ll wear the thermal underwear frequently. Machine washability and quick-drying fabrics add convenience, but some high-performance materials require gentle care. Cheaper options may wear out faster or lose insulating properties over time, so consider longevity if skiing regularly.

Price and Value

Higher-end options often feature advanced fabrics and better fit, but come at a premium. Budget-friendly sets can still provide decent warmth and comfort for casual skiers, especially when layered properly. Balance your skiing frequency, weather conditions, and budget to avoid overspending or underinvesting in your base layer. Remember, investing in quality can translate to better performance and longer lifespan.

Frequently Asked Questions

Should I choose thermal underwear with wool or synthetic fibers for skiing?

Wool, especially merino, offers excellent insulation, moisture-wicking, and odor resistance, making it a top choice for cold, damp conditions. Synthetic fibers like polyester or polyester blends tend to dry faster and are often more affordable, with good moisture management. The best choice depends on your skiing environment; wool is better for prolonged cold and damp weather, while synthetics suit high-output activities and quick-drying needs.

How tight should my thermal underwear fit for skiing?

The fit should be snug but not restrictive, allowing full mobility and effective moisture transfer. Compression fits can improve warmth and support, but overly tight layers might restrict circulation and cause discomfort during extended wear. Aim for a close but comfortable fit, especially around the waist, hips, and thighs, to maximize thermal efficiency without sacrificing comfort.

Can I wear thermal underwear all day without overheating?

Yes, if you choose fabrics designed for breathability and moisture-wicking, you can wear thermal underwear comfortably throughout your ski day. Layering is key; opt for lighter or more breathable options if the weather warms up or if you exert high energy. Avoid overly thick or non-breathable fabrics that trap heat, and monitor your comfort to prevent sweating and chilling.

Is it better to buy thermal underwear in a set or as separate pieces?

Buying a set ensures consistent fit and material compatibility, simplifying layering and overall comfort. However, separate pieces can allow for more customized layering, especially if you need different thicknesses or fits for various conditions. Consider your typical skiing environment and layering preferences to decide which option offers the best value and flexibility.

How often should I replace my thermal underwear for skiing?

High-quality thermal underwear can last several seasons with proper care, but signs of wear like thinning fabric, loss of elasticity, or persistent odors indicate it’s time for replacement. Cheaper options tend to wear out faster, especially if frequently washed or exposed to harsh conditions. Regularly inspecting your base layers and replacing them before they lose insulating properties can significantly improve your comfort and warmth on the slopes.

Conclusion

For most skiers, the Runhit Men’s Thermal Underwear Set offers the best balance of warmth, comfort, and affordability, making it the overall top choice. Beginners and casual skiers will find Amazon Essentials Men’s Slim Fit Thermal Long Johns a reliable and budget-friendly option. Those seeking premium performance should consider Spyder Women’s Thermal Underwear Set with advanced fleece technology. If you need a highly specialized layer for extreme cold, investing in a heavyweight, wool-blend set may be worth it. Ultimately, your choice should reflect your skiing frequency, typical weather, and personal comfort preferences.
