Soft, stretchy, versatile! Great for traveling.
Super soft and my favorite blanket for tropical/really hot countries as a super light blanket. I like to treat this whole bag with Permethrin as another layer against bugs (mosquitos) and it works well when I don't like the feel of the sheets where I'm staying. Also, it's fantastic for on a plane as a lap blanket or even a scarf. It is soft and stretchy and packs down so small I've even taken in on short weekend flights when I know Ill be sleeping on someone's couch. I've never actually used it for camping but I'm sure that would be great too. Super versatile.

Love Love Love
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!!!

Great for all temps
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.

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

Great bag liner!
Sleeping bag liners are great for keeping your bag clean and extending the life of the most expensive piece of the sleep system. It's also easier to wash, so you always have fresh "sheets" for your bag I have a Big Agnes Diamond Park bag, which has a more rectangular shape that most bags. It is also a sleep system that acts more like a bed, and this Sea to Summit bag liner works great with it. It also comes in handy if the weather it warmer than expected, as you can use it for sleeping on top of your bag, but not be completely uncovered. Finally, it is also nice to use with a quilt. Sometimes camping with a quilt can feel drafty, or you end up with cold spots. Using this liner with the quilt seems to even that out a bit and it more comfortable overall.

Weird and Stretchy
I like how compact this was, but the material was actually kind of heavy and super stretchy. Not convenient to climb in through the top and very uncomfortable while I was laying in it due to the stretchy material. I had to return it and get a different one that zips down the side.

short, narrow and lovely soft fabric
I'm 5.6 and wanted this to protect me from questionable sheets. It was too short and a bit confining. I like the fabric and color, but it's lacks the function I purchased it for.

Sehr angenehmer und weicher Schlafsackinlay als Schutz und zusätzliche Wärmeschicht

Not new. the liner was roughly folded in an open plastic pouch. Not happy! Not acceptable for a piece of cloth designed for sleeping.
