More Details on Our Top Picks
2-Pack Organic Baby Sleep Sacks, 100% Cotton, 0.5 TOG (Butterflies, 6-18 Months)
This set stands out for offering a versatile, durable option suitable for year-round use, thanks to its adjustable TOG and organic cotton construction. Unlike the thinner, single-season options like the JELLYMONI Baby Sleep Sack 0-6M, it provides a wider age range and more robust design, making it a practical investment for growing babies. Its ergonomic, wide-hip cut ensures natural movement, which is a key factor for healthy development. The limited pattern choices and fixed size range are tradeoffs, but for parents seeking a reliable, all-season solution, this product balances comfort and longevity effectively.
Pros:- Made from soft, breathable organic cotton for maximum comfort and safety
- Design allows natural movement with a wide hip area
- Suitable for all seasons with adjustable TOG ratings
- Durable, machine washable, and easy to change diapers
Cons:- Limited pattern options—only butterflies available
- Only available in a single size range (6-18 months)
Best for: Parents seeking a durable, all-season sleep sack that grows with their child from 6 to 18 months.
Not ideal for: Families needing a lightweight, ultra-simple option for quick trips or very hot climates, as its design is slightly bulkier than minimal models.
- Material:Cotton
- Size:6-18 months
- TOG:0.5
- Pattern:Butterflies
- Features:Breathable, Temperature-Regulating, Zipper Closure, Sleeveless
- Care Instructions:Machine Wash
- Weight Class:Lightweight
- Stretch:Medium Stretch
- Occasion:All seasons
Our verdict“This pick is ideal for families wanting a long-lasting, comfortable sleep sack that adapts to all seasons and grows with their baby.”
JELLYMONI Baby Sleep Sack 0-6M, 0.5 TOG, 100% Cotton Wearable Blanket
This sleep sack excels for infants up to 6 months, especially in warmer climates, due to its soft, pre-shrunk cotton and breathable design. Compared with the Organic Cotton Baby Sleep Sacks Swaddles 0-3 Months, it offers a roomy fit and simple two-way zipper for quick diaper changes, which is a real advantage during nighttime routines. Its lightweight fabric reduces overheating risks, making it suitable for summer months or well-ventilated nurseries. However, its limited size range and suitability only for warm weather mean it’s less versatile for colder months or older babies, which should be considered before purchasing.
Pros:- Soft, gentle on delicate skin
- Breathable fabric helps prevent overheating
- Easy diaper changes with a two-way zipper
- Roomy fit promotes natural movement
Cons:- Limited to infants up to 6 months old
- Not suitable for cold weather or larger babies
Best for: Parents of newborns in warm climates needing a breathable, easy-to-change sleep sack.
Not ideal for: Families in cooler regions or those with babies over 6 months, as it provides limited size and warmth.
- Material:100% Cotton
- Age Range:0-6 months
- TOG:0.5
- Color:Unisex neutral colors
- Features:Two-way zipper, pre-shrunk fabric, roomy fit
Our verdict“This sleep sack is perfect for quick, comfortable naps in warm conditions for the youngest infants.”
Baby Sleep Sack 0-6 Months, 3 Pack, 100% Cotton, Wearable Blanket, 0.5 Tog
This set offers excellent value with three sleep sacks in different patterns, ideal for families wanting multiple options for newborns. Its 0.5 tog rating makes it suitable for all-year use, comparable to the Organic Cotton Baby Sleep Sacks Swaddles 0-3 Months, but with the added benefit of multiple patterns and sizes. The two-way zipper and safety-lock feature improve convenience during nighttime diaper changes, though the limited size range (up to 24 months) may not meet the needs of growing babies beyond that stage. The variety makes it a practical choice for parents who prefer to keep a clean set on hand.
Pros:- Three sleep sacks in different attractive patterns
- Made from soft, breathable cotton
- Features a two-way zipper and safety-lock for convenience
- Durable and machine washable
Cons:- Limited to sizes up to 24 months
- Patterns are not customizable and may vary
Best for: Budget-conscious parents wanting multiple sleep sacks for frequent use and variety in patterns.
Not ideal for: Parents seeking high-end, customizable, or more season-specific options for older or larger babies.
- Material:100% Cotton
- Tog:0.5
- Includes:3 sleep sacks with different patterns
- Size:Multiple sizes up to 24 months
- Features:Two-way zipper, safety-lock
- Care Instructions:Machine washable
Our verdict“This set is a smart pick for families who want multiple, budget-friendly sleep sacks suitable for newborns and early toddlers.”
2-Pack Baby Sleep Sacks, Zipper Wearable Blanket, 100% Organic Cotton (BumbleBear, Large)
This set caters to slightly older infants and toddlers, providing a breathable, organic cotton alternative that emphasizes ergonomic fit. Compared with the 2-Pack Organic Baby Sleep Sacks, 100% Cotton, 0.5 TOG, it specifically targets 12-24 months, with a larger size and more established design features. The easy-to-use zippers with guards support safe, fuss-free diaper changes, but its limited to the larger size range, making it less suitable for newborns or early infants. Its breathable yet warm fabric makes it a good choice in moderate climates, though it may be too warm for very hot environments.
Pros:- Made from breathable, organic cotton for safety and comfort
- Easy-to-use zippers with protective guards
- Ergonomic design for natural movement
- Durable, machine washable fabric
Cons:- Limited to sizes for 12-24 months
- May be too warm in hot climates despite breathable fabric
Best for: Parents of toddlers requiring a safe, organic sleep sack that accommodates larger sizes comfortably.
Not ideal for: Families with newborns or in hot climates, as its larger size and slightly thicker fabric may be less suitable.
- Material:100% Organic Cotton
- Size:Large (12-24 months)
- Tog:0.5
- Number of Packs:2
Our verdict“This sleep sack is well-suited for active toddlers needing a safe, organic option that fits comfortably in the larger size range.”
Organic Cotton Baby Sleep Sacks Swaddles 0-3 Months, 2 Pack
This set is tailored for newborns up to 3 months, combining the benefits of sleep sacks and swaddles in a breathable organic cotton fabric. Compared to the JELLYMONI Baby Sleep Sack 0-6M, it emphasizes a cozy, arms-in or arms-out swaddle that encourages self-soothing. The adjustable design with a two-way zipper offers convenience, but its limited size range restricts use beyond early infancy. Its soft, breathable fabric supports gentle sleep, making it ideal for parents seeking a versatile, calming sleep environment for their newborns.
Pros:- Made from soft, breathable organic cotton
- Supports natural sleep position with adjustable arms-in or arms-out
- Two-way zipper facilitates easy diaper changes
- Grows with the baby through adjustable features
Cons:- Limited to 0-3 months size
- May be too warm for very hot environments despite breathable fabric
Best for: Parents of newborns who want a flexible, organic sleep solution that supports self-soothing and easy diaper changes.
Not ideal for: Families with larger or older babies, as it only fits up to 3 months and may be too warm in hot climates.
- Material:95% Organic Cotton, 5% Elastane
- Age Range:0-3 Months
- Weight:5-14 lbs
- TOG:0.8
- Number of Packs:2
Our verdict“This set fits well for parents seeking a cozy, adaptable sleep solution for their newborns with self-soothing benefits.”
Hudson Baby Unisex Baby Cotton Long-Sleeve Wearable Sleeping Bag
The Hudson Baby Long-Sleeve Sleep Sack stands out for its simplicity and affordability, making it a reliable choice for parents seeking a soft, breathable layer over pajamas. Unlike the Woolino, it doesn’t offer temperature regulation, so it’s better suited for moderate climates or indoor use. Its long sleeves add a layer of safety but limit versatility in warmer environments. The machine-washable design makes maintenance straightforward, though it cannot function as a standalone bed. Compared to more feature-rich options, this pick provides essential comfort without extra bells and whistles. It’s ideal for parents who want a no-fuss, safe sleep sack that keeps their baby cozy without the need for additional features.Pros:- Made from soft, breathable cotton for comfort
- Safe sleep design with long sleeves
- Machine washable for easy cleaning
- Affordable and high quality
Cons:- Limited to use over sleepwear, not standalone bedding
- Not suitable for hot climates or warm indoor temperatures
Best for: Budget-conscious families who need a simple, soft layer for safe sleep.
Not ideal for: Parents looking for all-season or temperature-regulating options, since it lacks adaptive features.
- Fabric type:100% Cotton
- Care instructions:Machine Wash
- Origin:Imported
Our verdict“This sleep sack is perfect for parents seeking a basic, breathable layer to ensure safe sleep at an affordable price.”
Woolino Ultimate Baby Sleep Sack – 4 Season Merino Wool Sleeping Bag, Organic Cotton Outer, Temperature Regulating Blanket, Adjustable Size 2–24 Months – Night Sky
The Woolino Sleep Sack excels in providing adaptable comfort across all seasons thanks to its natural Merino wool lining, a feature absent in the organic cotton-only Burt’s Bees option. Its temperature regulation helps prevent overheating in summer and chills in winter, making it ideal for families in fluctuating climates. The adjustable snaps and seat-belt openings offer a growth-friendly design, but the natural fibers demand careful laundering, unlike the Hudson Baby’s machine-wash convenience. While it’s more expensive, this pick offers a long-term, versatile solution for parents who prioritize natural materials and all-season use. Compared with the Burt’s Bees wearable blanket, it’s better suited for colder or variable environments due to its superior insulation.Pros:- Temperature-regulating merino wool helps prevent overheating and chills
- Adjustable and versatile design suitable for all-year use
- Trusted brand with industry awards and certifications
- Made from natural, breathable materials
Cons:- May be more expensive than synthetic sleep sacks
- Requires special care for natural materials
Best for: Parents seeking a durable, all-season sleep sack with natural temperature regulation for their baby from 2 months to 2 years.
Not ideal for: Families on a strict budget or who prefer low-maintenance, machine-washable options, as natural wool requires more care.
- Material:100% Merino Wool lining, 100% Organic Cotton outer
- Size:Universal size for 2–24 months
- Certifications:OEKO-TEX STANDARD 100
- Design Features:Double shoulder snaps, two-way zipper, seat-belt openings
Our verdict“This pick offers a premium, adaptable sleep solution for parents prioritizing natural fibers and year-round comfort.”
Burt’s Bees Baby Organic Beekeeper Infant Wearable Blanket, Unisex Swaddle
The Burt’s Bees Beekeeper wearable blanket combines organic cotton softness with thoughtful design features like a two-way zipper, making nighttime diaper changes simple. It’s comparable to the Woolino for its natural materials but lacks temperature regulation, making it less ideal for fluctuating climates. Its roomier fit supports active babies who kick and stretch, but parents should check size charts carefully to avoid a loose fit that could compromise safety. While it offers practicality and natural softness, its simplicity might feel underwhelming for those seeking advanced features. This product makes sense for parents who prioritize gentle, organic fabrics and easy diaper access over temperature regulation or adjustable sizing.Pros:- Made with GOTS-certified organic cotton for gentle skin contact
- Two-way zipper allows quick diaper changes
- Roomy design supports active babies
- Suitable for year-round use with different weights
Cons:- May require careful size selection for proper fit
- Limited color options and simple design
Best for: Parents wanting a soft, safe, and easy-to-change wearable blanket for active infants in moderate climates.
Not ideal for: Those in variable or colder environments who need integrated temperature regulation or adjustable sizing for longer use.
- Fabric type:100% Organic Cotton
- Care instructions:Machine Wash
- Origin:Imported
- Weight options:0.5 TOG, 1.5 TOG
Our verdict“This wearable blanket is ideal for parents seeking a natural, easy-to-change sleep sack for active infants in moderate climates.”
Yoofoss Baby Sleep Sack 0-6 Months, 0.5 TOG, 100% Organic Cotton, 3-Pack
The Yoofoss 3-pack offers a cost-effective way to outfit a newborn with organic cotton sleep sacks, each with a smooth 2-way zipper for easy nighttime changes. Compared to the Burt’s Bees Beekeeper, it provides a good balance of comfort and affordability, but the smaller size limits its use to the first 6 months. The lightweight 0.5 TOG fabric suits warmer climates or indoor use, though it might fall short in colder settings. The three-pack adds convenience but means parents must plan for size growth and laundering frequency. This set is best for budget-minded parents who want reliable, organic sleep sacks for early months without extra features.Pros:- Made from high-quality, organic cotton for softness and safety
- Easy-to-use double zipper design
- Includes three assorted colors for variety
- Promotes healthy hip development
Cons:- Limited to the 0-6 month size in this pack
- Lightweight fabric may not suit cold weather
Best for: New parents wanting multiple, affordable organic sleep sacks for infants 0-6 months.
Not ideal for: Families in colder climates or those looking for adjustable or all-season options that grow with their baby.
- Material:100% Organic Cotton
- TOG:0.5
- Size:0-6 Months
- Pack Size:3-pack
- Closure:2-Way Zipper
- Certifications:GOTS
Our verdict“This pack is suitable for budget-conscious parents seeking reliable, organic sleep sacks for early infancy.”
Burt’s Bees Baby Infant Wearable Blanket, Organic Cotton Beekeeper – Light Weight 0.5 TOG or Medium Weight 1.5 TOG
The Burt’s Bees Beekeeper wearable blanket offers a gentle, organic cotton sleep option with the flexibility of two weight options—light and medium—making it adaptable for various room temperatures. It’s similar in concept to the Woolino but lacks natural temperature regulation, which could be a shortfall for those in fluctuating climates. Its interior zipper guard and multiple sizes add safety and convenience, but the design remains simple, with limited color choices. Compared with the Yoofoss pack, it’s more versatile for different ages and climates, yet it may lack the specific features some parents seek. This product suits parents prioritizing organic fabrics and simple, safe solutions for growing infants.Pros:- Made of soft, organic cotton gentle on skin
- Safety features like interior zipper guard
- Suitable for various sizes and temperatures
- Easy diaper changes with zipper closure
Cons:- Limited color options
- Design may be too simple for some preferences
Best for: Parents needing a versatile, organic wearable blanket that accommodates different sizes and temperature preferences.
Not ideal for: Those looking for advanced features like adjustable sizing or temperature regulation built into the fabric.
- Fabric:100% Organic Cotton
- Weight Options:0.5 TOG, 1.5 TOG
- Sizes:Small to Large
- Care Instructions:Machine Wash
Our verdict“This wearable blanket offers flexible, organic comfort across multiple sizes, ideal for parents wanting simplicity and safety.”
Mosebears Unisex Baby Sleep Sack 1.0 TOG, Supersoft Rayon from Bamboo Wearable Blanket with 2-Way Zipper
The Mosebears sleep sack stands out for its luxuriously soft bamboo fabric, making it ideal for sensitive skin and year-round comfort. Its roomy, sleeveless design allows for ample movement and kicking, while the 2-way zipper simplifies diaper changes—a feature that surpasses the basic zipper of the Burt’s Bees Beekeeper blanket. Compared to thicker options like the Duomiaomiao 2.5 TOG sack, this pick offers a lighter feel suitable for warmer nights, though it may require layering in colder climates. Its fabric composition ensures breathability, but the care instructions are not detailed, which could be a concern for durability over time. This makes it a great choice for parents seeking a breathable, soft, and adaptable sleep sack for infants up to 24 months, especially in moderate climates.Pros:- Exceptional softness from bamboo fabric suitable for sensitive skin
- Roomy design supports natural movement and growth
- Easy to put on and take off with a two-way zipper
Cons:- Limited to babies within specified height and weight ranges
- Lack of detailed care instructions may affect longevity
Best for: Parents looking for a soft, all-season sleep sack that accommodates active babies and frequent diaper changes
Not ideal for: Families in very cold regions needing extra warmth, as this sack may not provide sufficient insulation in harsh winters
- Fabric:95% Rayon from Bamboo, 5% Spandex
- TOG Rating:1.0
- Design:Sleeveless, roomy fit, reinforced stitching
- Closure:2-way zipper with protectors
- Suitable Age/Size:0-24 months
Our verdict“This sleep sack is perfect for parents seeking a gentle, breathable option that works well across multiple seasons, with the caveat of needing additional layers in winter.”
Duomiaomiao 2.5 TOG Baby Sleep Sack – 100% Cotton Winter Long Sleeve Wearable Blanket
The Duomiaomiao 2.5 TOG sleep sack excels in providing warmth, thanks to its thick polyester filling combined with organic cotton outer fabric, making it ideal for colder nights. Unlike the lighter Mosebears, it prioritizes insulation, which makes it better suited for winter or drafty environments. However, its higher TOG rating limits its utility in milder indoor temperatures, where it could cause overheating. Its preshrunk cotton keeps sizing stable after multiple washes, but the weight and bulk might restrict movement compared to the more relaxed Mosebears design. This sleep sack is best for parents seeking a cozy, winter-ready option for infants up to 36 months, willing to manage its heavier feel.Pros:- Provides excellent warmth with thick polyester filling
- Made from soft, breathable organic cotton suitable for sensitive skin
- Preshrunk fabric maintains size stability after washing
Cons:- Too warm for indoor use in milder weather
- Bulkier design may restrict infant movement
Best for: Families in colder climates or homes with lower indoor temperatures needing a warm, durable sleep sack
Not ideal for: Parents in mild or warm environments who want a lightweight, all-season sleep sack
- Material:100% Cotton outer, Polyester filling
- TOG Rating:2.5
- Size Range:0-36 months
- Temperature Range:53.6°F – 68°F
- Closure:Zipper
- Care Instructions:Machine wash, tumble dry low
Our verdict“This sleep sack offers superior warmth for cold environments but is less versatile for year-round use in moderate climates.”
Burt’s Bees Baby Organic Beekeeper Infant Wearable Blanket, Unisex Swaddle
The Burt’s Bees Beekeeper blanket is a versatile choice, crafted from GOTS-certified organic cotton that’s gentle on delicate skin. Its lightweight design with a 0.5 or 1.5 TOG option makes it suitable for all seasons, especially when paired with appropriate clothing layers. The roomy, kickproof shape allows babies to move freely, similar to the Mosebears’ design but with a softer, more traditional swaddle feel. Unlike the heavier Duomiaomiao, it excels in warmer climates or indoor settings, though selecting the correct fabric weight is key to avoiding overheating. Its simple two-way zipper facilitates quick diaper changes, but fit depends heavily on height and weight, which may complicate sizing. This product suits parents wanting a gentle, year-round wearable blanket that promotes natural movement.Pros:- Made from GOTS-certified organic cotton, safe for sensitive skin
- Two-way zipper simplifies diaper changes
- Available in different weights for seasonal use
Cons:- Size and fit depend on height and weight, not just age
- Limited color options could affect style preferences
Best for: Parents seeking a lightweight, year-round organic sleep sack with easy diaper access for infants of varying sizes
Not ideal for: Families in extremely cold climates or those needing a very warm sleep sack for winter nights
- Fabric type:100% Organic Cotton
- TOG:0.5 or 1.5
- Design:Sleeveless, roomy, kickproof
- Closure:2-Way Zipper
- Care instructions:Machine wash
Our verdict“This blanket is a flexible, gentle option ideal for parents wanting a safe, easy-to-use wearable blanket for year-round comfort.”
2-Pack Organic Baby Sleep Sacks, 100% Cotton 0.5 TOG (Bunnies, 6-18 Months)
These organic cotton sleep sacks excel in providing a comfortable, ergonomic fit with their wide hip area, supporting natural movement for babies from 6 to 18 months. Compared to the lightweight Burt’s Bees Beekeeper, they offer a slightly thicker fabric—though still lightweight—making them suitable for indoor environments or mild weather. Their 0.5 TOG rating makes them less ideal for colder nights unless layered, but they shine in balancing breathability with enough warmth for transitional seasons. The two-pack offers good value, yet their limited age range and moderate warmth mean they aren’t best for winter in colder regions. Overall, this set is a smart choice for parents prioritizing ergonomic design and affordability in moderate climates.Pros:- Made from soft, breathable organic cotton
- Ergonomic design with wide hip area for natural movement
- Cost-effective two-pack provides great value
Cons:- Limited to 6-18 months, less suitable for older or younger infants
- May not provide enough warmth for winter without layering
Best for: Parents wanting a breathable, ergonomic sleep sack for toddlers in transitional seasons or mild indoor environments
Not ideal for: Families in cold climates needing extra insulation or in very warm climates where 0.5 TOG might cause chilliness
- Material:100% Organic Cotton
- TOG:0.5
- Age Range:6-18 months
- Design:Full-length, wide hip area
- Colors:Bunnies
- Number of Packs:2
Our verdict“This set offers a balanced, ergonomic solution for babies in moderate climates, with good value for families focused on natural fabrics.”

Factors to Consider When Choosing Organic Cotton Baby Sleep Sacks
Choosing the right organic cotton baby sleep sack involves considering several key factors. Beyond fabric quality, it’s important to think about safety features, seasonality, and ease of use. Understanding these elements can help prevent common mistakes, such as selecting an incorrect Tog rating or opting for a product that’s difficult to wash. A well-chosen sleep sack not only keeps your baby comfortable but also promotes safe sleep practices. Here are the main factors to keep in mind when shopping:Material Quality and Organic Certification
Ensuring the sleep sack is made from certified organic cotton guarantees the fabric is free from harmful chemicals, which is especially important for sensitive baby skin. High-quality organic cotton also tends to be softer, more breathable, and durable, providing long-lasting comfort and safety. Be cautious of products claiming to be organic without proper certification, as non-organic cotton may contain residual pesticides. Investing in certified organic options often means paying a bit more upfront but provides peace of mind and better long-term value.
Safety Features and Fit
Look for sleep sacks with secure, smooth zippers that won’t pinch delicate skin or cause discomfort. The fit should be snug but not tight, with enough room for movement without excess fabric that could pose a suffocation risk. Consider designs with zipper covers or protected zippers to prevent accidental opening. Proper fit and safety features reduce the risk of hazards and give parents confidence that their baby sleeps securely.
Tog Ratings and Seasonality
The Tog rating indicates the warmth level of the sleep sack. Lower Tog (like 0.5) suits warm environments or summer months, while higher Tog (around 2.5 to 3.5) is better for cooler weather or winter. Choosing the right Tog helps prevent overheating or chilling, both of which can interfere with safe sleep. Some sleep sacks are designed as all-season options, often with removable liners, offering flexibility for year-round use.
Ease of Use and Maintenance
Parents benefit from sleep sacks that are simple to put on and take off, especially during middle-of-the-night feedings or diaper changes. Features like two-way zippers or large arm openings add convenience. Washability is equally important; machine-washable fabrics that retain softness over time are ideal. Consider whether the product’s design minimizes pilling or shrinkage, which can affect fit and comfort after multiple washes.
Price and Value
While premium organic sleep sacks often incorporate advanced features or higher-quality materials, budget-friendly options can still meet safety and comfort standards. Bundles or multi-packs typically offer better value, especially for growing babies or parents who prefer to have spares. Be mindful of the balance between cost and features; investing in a slightly more expensive, safer, and more durable product can save money and stress in the long run.
Frequently Asked Questions
Are organic cotton sleep sacks safer than synthetic ones?
Yes, organic cotton sleep sacks tend to be safer because they are free from harmful chemicals, pesticides, and dyes common in synthetic fabrics. Organic cotton is also less likely to cause allergic reactions or skin irritation, making it a better choice for sensitive newborns and infants. While synthetic options may be cheaper or more colorful, choosing organic cotton prioritizes your baby’s health and reduces exposure to potential irritants.
What Tog rating should I choose for different seasons?
For warm weather or hot climates, a Tog of 0.5 or 1 is usually sufficient to prevent overheating. During cooler months or in air-conditioned rooms, a Tog of 2.5 or higher provides extra warmth. All-season sleep sacks often feature removable liners or layered designs that can adapt to changing temperatures. Matching Tog ratings with your home’s climate ensures your baby stays comfortable and safe during sleep.
How do I know if a sleep sack fits my baby properly?
A well-fitting sleep sack should be snug around the shoulders and chest without restricting movement or causing discomfort. There should be enough room for your baby to wiggle arms and legs freely, but not so loose that it risks slipping over the face. Most brands offer size charts, and choosing the right size based on your baby’s weight and height helps ensure safety and comfort. If in doubt, opting for a slightly larger size can accommodate growth while maintaining a proper fit.
Are multi-packs worth it for organic cotton sleep sacks?
Multi-packs often provide better value, especially if your baby is growing quickly or if you want spares for laundry day. They can also be useful for parents who prefer to rotate sleep sacks frequently for hygiene or temperature changes. However, ensure each sleep sack in the pack maintains the same high safety and quality standards. Sometimes, buying individually tailored or higher-end options may be preferable if your baby has specific needs or sensitivities.
Can I use the same sleep sack year-round?
Using the same sleep sack year-round depends on its Tog rating and your home’s climate. All-season sleep sacks with adjustable features or removable linings can be suitable for different seasons, offering versatility and convenience. Otherwise, you might need to switch between lighter and heavier options to keep your baby comfortable and safe. It’s important to monitor your baby’s temperature and adjust clothing or sleep sacks accordingly to avoid overheating or chilling.
