Should You Wear Pajamas In A Sleeping Bag?
Camping in the cold can be downright miserable if you’re not prepared. Nothing ruins a camping trip faster than failing to prepare for cold weather. Obviously you need the usual cold weather sleeping gear: sleeping bag, sleeping pad, and sleeping bag liner, but what about clothes? Do you need to wear lots of layers to stay warm at night or can you strip down. What should you wear in a sleeping bag?
Let’s start off with a simple question with a not so simple answer. Should you wear clothes in a sleeping bag? A lot of people think that you don’t need pajamas if you’ve picked the right sleep system.
They actually believe that sleeping naked in a sleeping bag will increase warmth, but that’s an old wives tale. There are a few cases where that may be true, like if your clothes are wet, they cut off circulation, or you’re wearing so much that it compressing the sleeping bag’s filling, but 99% of the time it will be warmer to wear clothes to bed.
Wearing clothes to bed adds another layer of insulation to trap body heat. Layering clothing will increase the temperature rating of your sleeping bag making an underrated bag perform below its temperature rating.
Plus wearing clothes will reduce the dirt and sweat that gets into your sleeping bag delaying wash cycles. Every time you wash your sleeping bag the down/synthetic fill contracts making it less effective. Using a sleeping bag liner is another way to protect your bag and increase the amount of time between wash cycles.
Understanding Different Pajama Materials

Choosing the right materials for your sleepwear can significantly enhance your camping experience. If you sweat during the night or simply want to stay comfortable, moisture-wicking fabrics are a game-changer.
These specialized fabrics pull moisture away from your skin and allow it to evaporate, helping you stay dry and comfortable throughout the night. Pajamas made from moisture-wicking materials like polyester or merino wool will ensure you don’t wake up drenched, allowing for a restful night’s sleep.
When camping in colder climates, the importance of wearing thermal materials cannot be overstated. Fabrics such as fleece or heavier-weight merino wool trap body heat effectively, keeping you warm even when temperatures drop.
It’s really hard to get uncomfortably sweaty in merino wool since it can absorb 30% of its weight in water without feeling wet. You can be a sweaty mess and your wool base layers will feel completely dry. Add in antimicrobial properties and odor resistance, and you have the perfect camping pajamas.
Smartwool is my go to brand of merino wool clothing. I have their sweaters, base layers, socks, winter hats. It’s actually starting to get a little ridiculous since my wife buys Smartwool every Christmas and birthday.
Thermal sleepwear is designed to insulate while remaining lightweight, making it perfect for layering under your sleeping bag without adding unnecessary bulk. This combination of warmth and comfort is essential for enjoying those crisp nights under the stars.
For those warm summer nights, breathable options become crucial for a good night’s rest. Fabrics like cotton, moisture-wicking athletic fabrics, and linen allow air to circulate, helping to regulate body temperature and prevent overheating. Lightweight and comfortable, these materials offer just the right amount of coverage without stifling you during muggy nights.
You should avoid cotton clothing during the day, but I have no problem sleeping with it at night. A comfortable cotton hoody is one of my favorite things to wear around a campfire on chilly nights.
Choose Multi-Use Camping Pajamas
Whenever I’m shopping for new camping pajamas I try to find multi-use outfits. I like to choose pajamas that can be worn more than once during the trip. That’s why I almost always go with merino wool base layers.
In colder weather, I typically carry two pairs of Smartwool merino wool bottoms and tops. I wear my first set of bottoms/tops all day on the trail, set up camp, eat dinner, do camp chores, and get ready for bed.
Right before I head to bed, I’ll throw on my second pair and hang the first pair up in the corner of my tent using clothespins. I’ll wear my sleep clothes as my base layer the following day and repeat the process. By the time I finish hiking that day my first days base layers are completely dry and don’t have any odor whatsoever.
Sometimes I’ll throw in a 3rd set of base layers on longer trips. Wool is great at fighting odors and bacteria, but I feel a little dirty after wearing the same clothes for a week. You can do the same thing with Smartwool socks and Underwear during the summer.
You’re really missing out if you don’t have merino wool socks and underwear. It doesn’t matter how long you hike in merino wool socks and under, they don’t get sweaty. Switching over to merino wool completely solved the chafing and blister issues I was dealing with after long hikes.
Layering Techniques for Optimal Comfort

Temperatures can fluctuate dramatically between day and night. This is where mastering the art of layering your sleepwear becomes crucial for a comfortable night’s rest. The key is to create a system that can adapt to changing conditions while ensuring you stay warm without overheating.
Start with a snug base layer, such as moisture-wicking long johns or lightweight thermal tops, which will keep you dry by pulling sweat away from your skin. This is particularly important during those chilly nights when you’re wrapped up in your sleeping bag; a good base layer sets the stage for warmth.
Next, consider adding a mid-layer for additional insulation. Fleece or wool tops work wonders in providing warmth without bulk. A fleece pullover can trap heat while still allowing for breathability if you’re camping in colder weather.
Depending on how chilly it gets, you might even want to opt for an insulated vest as your mid-layer. This layering approach not only helps regulate your body temperature but also allows you to easily adjust based on how warm or cool you feel throughout the night.
Lastly, an outer layer can be beneficial if you’re expecting dampness or wind during your camping trip. Lightweight, packable jackets made of water-resistant material can help shield you from the elements while still being comfortable enough to wear inside your tent. Just make sure it’s completely dry before crawling in your sleeping bag.
In warmer conditions, consider ditching the outer layer altogether or opting for lighter options that won’t suffocate you in the heat. Always be prepared to modify your layers based on real-time weather conditions; if you find yourself too warm, simply remove a layer and keep it nearby for later use.
Different Layers
- Base Layer: In the summer, your base layer will usually be underwear, gym shorts, and a t-shirt. Your sleeping bag provides plenty of insulation so you don’t need to wear a middle insulating layer or outer layer. On cold nights you’ll want to wear long johns, pajama pants, or sweatpants and long sleeve shirt like a merino wool base layer. I usually merino wool long johns (these ones), sweatpants, merino wool socks (Smartwool Socks), and a long sleeve merino wool shirt (my favorite).
- Middle Layer(insulation): The middle layer is used as the insulating layer. Most people wear either a fleece jacket or light down/synthetic jacket and a winter hat. I like to wear a hood, but that’s uncomfortable for some people. If you’re insulating layer is comfortable to wear on its own during the daytime temperatures it should be perfect at night. You can also wear snow pants if your legs get cold easily.
- Outer Layer (Shell Layer): I highly doubt you’ll need to wear an outdoor shell layer in a sleeping bag. It won’t hurt on extremely cold nights, but the outer layer is mostly for wind/water protection. Your tent and sleeping bag provide enough protection from the outside weather so you should be fine without a shell layer.
Choosing the Right Pajama Fit
When it comes to selecting sleepwear for camping, the fit of your clothing can significantly impact the quality of your sleep. Comfortable sleepwear allows for freedom of movement, which is essential after a long day of hiking.
If your sleepwear is too tight, it can restrict circulation and cause discomfort, making it difficult to to fall asleep. On the other hand, overly loose clothing may lead to drafts and reduce the effectiveness of your layering techniques, leaving you feeling cold during the night. Finding that perfect balance is crucial for getting a good nights sleep.
Tight-fitting clothing can provide better insulation by trapping heat close to your body, but it’s important to ensure that it doesn’t constrict movement. A snug base layer made from moisture-wicking fabric can keep you warm and dry without feeling restrictive.
Practical Clothing Options for Campers
Versatility is key when it comes to selecting camping sleepwear. Pajamas and thermal sets are two of the most popular choices among outdoor enthusiasts. Pajamas made from moisture-wicking materials keep you dry and comfortable, even after a long day of hiking.
Thermal sets, on the other hand, are ideal for those chilly nights, providing an extra layer of warmth without sacrificing comfort. Consider investing in a pair of fleece-lined thermal bottoms paired with a moisture-wicking long-sleeve top; this combination can easily transition from lounging around the campfire to snuggling into your sleeping bag.
Choosing sleepwear from outdoor-specific brands offers additional benefits that regular clothing may not provide. These brands design their products with unique features tailored for campers and hikers. They almost always have quick-drying fabrics, odor resistance, and enhanced breathability.
For instance, brands like Patagonia and REI offer sleepwear that incorporates eco-friendly materials while ensuring maximum comfort. Investing in high-quality sleepwear will allow you to get a good nights rest rather than worrying about discomfort during the night.
Another option worth considering, is using your existing outdoor gear as sleepwear. Most hikers already own moisture-wicking gear that they wear to hike. Lightweight base layers made from merino wool or synthetic blends are excellent choices since they provide warmth without bulk and wick moisture effectively.
I really like Smartwool base layers, but there are other more affordable options you can buy. Amazon has loads of merino wool base layers that you can sort through, but I haven’t tried any of their cheaper options. Just make sure you purchase 100% merino wool instead of synthetic blends.
A snug-fitting base layer top and bottom can keep you warm while still allowing for freedom of movement. However, it’s essential to ensure that your gear is clean and free from any harsh odors before slipping into it for the night. By creatively mixing and matching your camping wardrobe, you can maximize comfort while minimizing packing space, making your outdoor adventures even more enjoyable.
A Few Clothing Options
- Base Layer Shirt: I normally go shirtless in the summer, T-Shirt in the spring/fall, and wear a merino wool thermal shirt on colder nights. Merino Tech Merino Wool Baselayers are affordable thermal shirts and they’re extremely comfortable. Smartwool shirts are a little bit warmer, but almost twice the price!
- Comfortable Pants or Shorts: Wear lightweight gym shorts in warm weather and long johns, pajama pants, or sweatpants in cold weather. I like to wear my merino wool long johns under a pair of sweat pants on chilly nights. You may even want to wear lightweight snow pants over your base layer in the winter.
- Merino Wool Socks: Sleeping bags provide consistent insulation throughout the bag, but most of your body heat is released through your torso. That means the center of your bag will be warm and it will get colder as you go farther down the bag. Wearing a pair of merino wool socks to bed will keep your feet warm evening out the temperature extremes in your bag.
- Light Jacket or Sweater (Cold Weather): You may want to put on a light jacket or sweater to keep your chest warm in cold weather. This isn’t necessary with a sleeping bag that’s rated for extreme temps, but it will really help if nighttime temps are nearing your bags rating. I carry a lightweight fleece jacket to wear at night, but a down puffer jacket (like this one) will keep you warmer at a similar trail weight. Feel free to layer up multiple jackets, but try not to contract the outside baffles on your sleeping bag.
- Winter Hat (Cold Weather): Your head won’t be protected in a sleeping bag so it’s important to wear a winter stocking cap on cold winter nights. Sleeping bag hoods provide some warmth while blocking the wind, but you should really consider wearing winter hat to bed in the cold.
- Mittens Optional (Cold Weather): There’s less blood circulating through your hands and feet so they’ll get colder than the rest of your body. I have a hard time sleeping in mittens, but a lot of cold weather campers wear them to bed. They’ll definitely help keep your hands warm so it’s worth considering.
Accessories to Enhance Sleep Comfort
When it comes to sleepwear for camping, the right accessories can make a significant difference in your overall comfort and warmth. You might not sleep in socks at home, but I highly recommend wearing merino wool socks on the trail.
They never feel wet or scrunch up in your shoes, so they’re far less likely to cause blisters on long hikes. Then at the end of the day you can wear the same socks to bed and keep your feet warm. Sleeping bags are notorious for having less padding down by your feet. I know if that’s because the stuffing shifts, but your feet might freeze if you don’t have a decent pair of socks to sleep in.
Wool or synthetic blends are excellent choices as they provide insulation even when damp, ensuring your feet stay cozy throughout the night. I like Smartwool cold weather cushion socks, but they can be pricey. Amazon has loads of budget options if you don’t want to spend that much on quality socks.
A warm hat can also work wonders, especially during chilly nights. By retaining heat from your head, a hat can help regulate your body temperature and keep you snug as you drift off to sleep.
Another accessory that shouldn’t be overlooked is a sleeping bag liner. This versatile piece not only adds an extra layer of warmth but also serves to keep your sleeping bag clean and prolong its life. When choosing a liner, look for materials that offer both breathability and insulation, such as silk or lightweight fleece.
These fabrics can enhance the thermal efficiency of your sleeping bag without adding excessive bulk, making them ideal for all types of camping trips. Some liners even come with added features like built-in hoods or zippered pockets, providing an extra touch of convenience and comfort.
Sleeping Pad R-Values and Sleeping Bag Temperature Ratings Explained

The clothing you wear in your sleeping bag will help keep you warm, but you won’t be comfortable with a poorly chosen sleeping bag/pad. When it comes to warmth, there are two main factors you need to consider when choosing a sleep system. You have to consider the sleeping bags temperature rating and sleeping pads R-Value.
It doesn’t matter what type of bag/pad you choose! If you figure out those two things you should be comfortable sleeping at night. Here’s a brief overview of temperature ratings and R-Values.
- Sleeping Bag Temperature Rating: Sleeping bag temperature ratings don’t tell you the temperature rating that you’ll be comfortable at! It’s actually the temperature rating where you may start to experience safety issues. So you’ll be freezing if the temperature dips close to the bags advertised temperature rating. I recommend buying a sleeping bag that’s at least 15°F colder than expected nighttime temperatures. You can further pad the rating with a sleeping bag liner and lots of layers.
- Sleeping Pad R-Value: Sleeping pads protect your body from heat loss through the cold ground. As you go into higher R-Values the pad will be warmer. It doesn’t matter what type of sleeping pad you use as long as the R-Values suitable for the weather conditions. You can stack foam and inflatable/self-inflating pads to increase R-Value in cold weather. Look at the R-Value chart above to figure out a bag for your needs.
Sleeping Bag Liners Will Increase Your Bags Temperature Rating

Once you have a sleeping bag and pad picked out you should seriously consider picking up a sleeping bag liner. A sleeping bag liners main job is to protect your bag from sweat, dirt, body oils, salt, and anything else that’s on your body, but it will also pad the temperature rating.
How much the liner adds to the temperature rating will depend on the liner you choose. Sea to Summit is the king of sleeping bag liners, but they can be expensive. I highly recommend their liners, but go with a cheap Coleman liner if you’re on a tight budget. It’s affordable, extremely durable, and adds 12°F. The only downside is that it’s heavy at 1lb 10oz.
There are two Sea to Summit liners that 99% of people choose between. The Sea To Summit Reactor Liner adds 25°F to your bags temperature rating, and the Reactor Fleece Insulated Liner adds 32°F to the bags rating. The reactor liners is a little bit lighter and comes in different lengths so go with that one if you use an oversized sleeping bag.
Staying Cozy Without Overheating
One of the biggest challenges can be finding that perfect balance between warmth and comfort. Using a sleeping bag can sometimes lead to overheating, especially if you’re bundled up in too many layers or wearing materials that trap heat. It gets really bad in the morning once the sun starts beating down on your tent.
Recognizing the signs of being too warm while sleeping is crucial for a good night’s rest. If you find yourself frequently tossing and turning, kicking off your sleeping bag, or waking up with a clammy feeling, it’s likely that you’re overheating.
Pay attention to your body’s signals; sweating is a clear indicator that your sleep environment is too warm. If you wake up feeling restless or irritable, consider adjusting your layers or the temperature of your sleeping space to create a more comfortable atmosphere.
To effectively adjust your sleep environment, start by assessing how you’ve layered your sleepwear. If you’re feeling too warm, try removing an outer layer or unzipping your sleeping bag for ventilation.
Additionally, consider the placement of your sleeping bag; if you’re camping in a tent, don’t sleep directly on the ground. Use a sleeping pad with a suitable R-Value for the conditions. Look at the R-Value chart above for more info.
By being mindful of your sleepwear choices and making small adjustments to your sleep environment, you can ensure cozy nights without the discomfort of overheating. Remember that staying cool while camping is just as important as keeping warm; striking that balance will help you enjoy restful nights filled with sweet dreams under the vast sky.
Packing Your Sleepwear for Camping Trips
When preparing for a camping trip, packing efficiently can make all the difference in your outdoor experience. Adopting best practices for folding and storing your clothes can save valuable space in your backpack.
One effective method is the roll-and-pack technique: instead of folding your sleepwear flat, roll each piece tightly. This not only minimizes wrinkles but also allows you to maximize space, making it easier to fit other essentials into your bag. Additionally, consider using packing cubes or compression bags to keep your sleepwear organized and compact, allowing for quick access during your adventure.
Choosing lightweight and compact options for travel is essential for campers who want to minimize their load. Look for sleepwear made from synthetic materials or lightweight merino wool, which offer breathability without bulk.
For instance, a moisture-wicking base layer can double as both sleepwear and an extra layer during chilly nights around the campfire. It might not be the fashionable choice, but opting for versatile pieces, such as zip-off pants that can convert into shorts or long-sleeve shirts that provide sun protection, not only streamlines your packing process but also enhances your overall camping experience.
Keeping your sleepwear clean during multi-day trips is another important consideration. To avoid packing dirty clothes back into your bag, bring along a mesh laundry bag to separate worn items from fresh ones. If you’re camping in a location with access to water, consider bringing a small bottle of biodegradable soap to wash your sleepwear on the go.
Quick-drying fabrics can be a lifesaver here, as you can wash them in the evening and have them dry by morning. Incorporating these simple sleep tips for campers will ensure that you stay comfortable and cozy, ready to enjoy restful nights under the stars.
Remember That Spring and Fall Weather is Unpredictable
Remember that spring and fall weather can be unpredictable. It can be 60°F on your first night and drop into the 30s the rest of the trip. You may even run into 40°F temperature swing between day and night temperatures. Try to look at the weather forecast, but plan on extreme temperature swings.
Bring extra clothes and a sleeping bag liner to add versatility to your sleep system. Wear extra layers on cold nights, use your sleeping bag liner, and bags zipper to adjust the temperature of your gear. You should be able to handle anything with lots insulation of layers to choose from.
It’s Always Easier to Remove Layers
Every additional layer adds more insulation between you and the cold outside air. Try to keep heat close to your body and regulate temperature by zipping and unzipping your bag. Start off the night with lots of layers and slowly ditch them as you overheat during the night.
Throughout the night the temperature will probably swing 10-20 degrees. If zipping and unzipping your bag isn’t enough you can always take off and put on additional layers in the middle of the night. I usually keep a light jacket stuffed in my sleeping bag so I can quickly toss it on if I get cold. Keeping it in your bag will keep the jacket warm so you won’t get a temperature shock like you’d get from a jacket stored in your pack.
Wrapping Up Your Sleepwear Choices
In conclusion, selecting the right sleepwear for camping is crucial for a cozy and restful night outdoors. The right materials, fit, and layering techniques can make all the difference in your comfort level. Remember to consider the weather and your personal preferences when choosing what to wear while you sleep under the stars.
Don’t hesitate to experiment with different options until you find the perfect combination that works for you. Whether it’s breathable fabrics for warm nights or thermal layers for chilly evenings, there are plenty of choices out there. So gear up, get comfortable, and enjoy those peaceful nights in nature!
