Best Camping Sleeping Bag Liners of 2025

"I recently bought this product for my walk on the Portuguese Camino, and it was absolutely perfect for staying in hostels along the way. I appreciate how packable it is and the roominess, plus it's easy to wash and dry. The only downside for me was the attached pillow cover; as a side sleeper, it felt a bit awkward, but overall, I consider it a great purchase."

"I used this sleeping bag liner over a four-day trek, and I found it to be both comfortable and spacious. I especially loved that I could put my pillow inside the liner, and it stayed in place without slipping away from me."

"As a plus-sized woman, I found this liner to have plenty of room for movement while sleeping. The zippers on both ends are a fantastic feature, allowing me to keep my feet exposed if I want. It's been a great experience overall!"

“I didn’t expect to enjoy this liner due to my restlessness and claustrophobia, but it turned out to be a wonderful addition for my cooler backpacking trips. It kept me toasty warm in upper 20s temperatures and served as a leg warmer during breakfast. I’m really glad I purchased it!”

“I’ve used this liner in cold backpacking conditions and it performs well. I’d definitely recommend it!”

“As a cold sleeper, I was worried about the temperatures dropping during my last trip, but this liner kept me warm enough that I woke up sweating! I even wore it around camp because it’s so functional.”

"I spent September hunting in Idaho and Colorado, and this liner was a game changer. It kept me warm and comfortable on cold nights, and I was surprised by the mobility it allowed. After 30 days of various weather conditions, it held up perfectly, and I highly recommend it!"

"I absolutely love this sleeping bag liner! During our backyard camping adventure, it provided a thick, comforting layer that kept me warm, even in a zero-degree bag. I realized it adds substantial heat, likely around 20 degrees, and while I overheated a bit, I feel confident it will keep me warm when needed!"

"This is my first liner, and I got it mainly to protect my sleeping bag from sweat and dirt. It’s made of soft fleece and is well-constructed. While I initially wished it had a zipper, I realized that would leak heat. The single drawstring could be better, but overall, it’s a great product!"

"I recently took this on a camping trip in Big Bend during October 2024, and I absolutely loved it! It felt like sleeping in a giant T-shirt, allowing me to move freely without feeling tangled. The nights were in the lower 60's F, and it provided some warmth alongside my Big Agnes sleeping bag. I believe even a full-size man would find it comfortable. If you're considering this liner, just go for it!"

"I was surprised by how well this thin liner worked on my last trip in colder weather. It kept me warm and became a cozy option when my sleeping bag got too hot. I felt like a little burrito! The tip about getting into it while standing was really helpful too."

"I'm familiar with this brand and decided to try this liner. I was not disappointed! It's well made and incredibly soft. It adds some extra warmth to my sleeping bag and keeps it fresher longer. I also plan to use it during hotter nights for a light but cozy option. Highly recommended!"

"I bought this for backpacking to make my sleeping pad and quilt feel more comfortable. This acts like a sleeve around the pad, making it feel more like a traditional bedsheet underneath me. Improved sleep for a very small weight penalty and takes up very little space in my bag. It's great!"

"I'm using this differently than advertised and it's working great! We backpack with our dog a lot and have expensive, fragile sleeping pads. After the dog put a hole in one of the pads, I bought these to use as covers. So far so good on several trips. We leave them on when we deflate and just roll them up with the pad. Comfy to lay on too with our light quilts. Sure, they add a bit of weight, but I don't stress about the dog and the pads as much, and the trade-off seems well worth it."

"I find this to be quite comfortable and roomy, and I'm on the 'fluffy' side (5'6"/180 lbs). It weighs next to nothing."

"For years, I struggled with sleeping bags that promised warmth but left me cold. I finally found the Deer Hunter sleeping bags from Teton Sports, rated for -35 deg F survival, and they truly deliver. I also purchased a Teton cotton liner, which I’ve used multiple times. It provides an extra 12-15 deg F warmth, perfect for cooler nights. The construction is solid, and it even comes with a carrying bag. With a price of $29, I consider it a five-star item!"

"My family and I love camping, but my boyfriend and I needed a solution for our different sleeping pad preferences. After some research, I discovered this product that holds our full-sized sleeping pads together perfectly. It's soft, machine washable, and helps us stay close while minimizing the hassle of sheets. I highly recommend it for those who want to cuddle on camping trips!"

"I initially thought this 'sheet set' would be a traditional sleeping bag, but it's actually quite different. It’s sewn up the sides with Velcro tabs, making it somewhat tricky to get in and out of, especially in a cramped tent. Nonetheless, I found it bearable for a night. I plan to make some alterations for easier access, but for the price, it’s not a bad option!"

"I used this as a sleeping bag liner and for motels. It feels nice and is lightweight, which was perfect for my trip from chilly San Francisco to hot Baja!"

"I bought this for a hiking trip in the Annapurna circuit. It was wide, pleasant, and comfortable. I found it very suitable for sleeping in a tent or even on its own."

"The quality is good and comfortable. It's easy to roll up and store after use, making it very convenient for my travels."

"I went camping in the snow, which isn't my favorite, but I didn't want to miss out! I have a great sleeping bag but needed that extra warmth. This liner is not lightweight for a backpack, but it was perfect for a few miles—totally worth the weight! It snowed outside my tent, and I was toasty and comfortable inside my 20° bag with this fleece liner."

"I found this liner to be nice and light, and it doesn't take up much space. It's very warm and fits nicely in my mummy bag."

"The material is nice, and it shipped quickly. It packs down small but comes in a normal sleeping bag sack without tension straps like the picture shows."

"I used this heated sleeping pad with a 32,000 mAh rechargeable battery for a winter van camping trip. The pad was too hot on high, but low and medium settings were perfect. The battery lasted until about 4:00 AM. It heated up quickly and was comfortable all night. I recommend a stronger battery or a backup. So far, I'm satisfied!"

"When I took this on a 30-day mountain hunt, it broke on the second day due to wire separation. While it was comfortable and warm when functioning, I was disappointed it failed so quickly after purchase. It’s a shame because I had high hopes for it."

"I almost didn't buy this due to poor reviews, but I found that the expectations were too high for a USB heating pad. It only draws 9 watts on high, but it performs well inside a sleeping bag, trapping warmth effectively. I use it on a tri-fold mattress in my SUV, and it works perfectly with added insulation."
