Sea to Summit Comfort Blend Sleeping Bag Liner

I love this thing. It’s so comfy and worth the little bit extra weight for shorter backpacking trips and certainly for camping. In the cold it kind of swaddles you and the warm temps you can unzip your bag but still feel covered. Material is very soft and good quality. I bought this and another less expensive version and this one is def worth the few extra bucks. I kinda want to sleep in it all the time. Read more

I recently used this for some warmer weather camping in Florida for about a week. Temperatures ranged from the low 70's to the 40's. Some days I used only this and it provided a nice, lightweight covering for warmer nights. For the cooler nights, I coupled this with my top quilt to get extra warmth and it worked perfectly. I love having the liner as it is so much easier to wash than the top quilt or a sleeping bag itself. It is also a nice, lightweight way of adding extra warmth/layers and comfort. I am also a side sleeper and appreciated the stretch this liner provides in being able to stretch myself out a little more. Great value and totally worth it. Read more

That’s nice, a little bit skinny Read more

Soft and comfy. Warm as a sleeping bag liner or on its own for nights that aren’t as cool. Read more

In warmer weather, in lieu of a sleeping bag, I use this as my sleeping "bag" and use a camping blanket/quilt for additional warmth. It's a great product. Very comfy. Reminiscent of sleeping with a sheet made of tshirt fabric. Adds a little weight to your backpacking setup, but compresses nicely. Read more

Use for hotel travel. Lightweight. Washes well but noticing small fabric tears in various places. Read more

This thing is thin and I didn't think it would really help much, but to my surprise it helped me keep warmer on my last trip in colder weather. Not only that, but the temperature varied and it became a great warm weather option when my sleeping bag got too hot. I felt all cozy like a little burrito in this. Doesn't look like much, but I am really pleased with my purchase. The review that mentioned getting into it while standing before going into your sleeping bag was really helpful. Read more

I just used this on a camping trip in Big Bend during October 2024 and I loved it! It is like sleeping in a giant T-shirt. You can move in any direction and it stretches every which way. I am a side sleeper that switches sides multiple times per night and I never felt tangled up or constricted in this at all. It is shocking how stretchy it was. The two nights that I used this liner I believe the temps got in the lower 60's F. I was using a Big Agnes Anvil Horn sleeping bag and a Big Agnes sleeping pad, which had an R value of 4.something. I alternated with using the sleeping bag to cover just my legs and sometimes my full body, so the liner did provide some warmth. I am a female, 5'6", 155 lbs, but I am positive that a full size man would be extremely comfortable in this sleeping bag liner and would not feel constricted. My sleeping bag was the only thing limiting any of my movements. If you are on the fence and considering purchasing this liner, DO IT! It is great!!! Read more
