Rated 4 out of 5 by from Fits the bill I bought this for my BA sleeping bag. The last few times I was out it was a little warm and unzipping the bag left me just a little uncomfy. I also, while being too warm, began to perspire a bit which caused the bag to feel muggy. So I bought this and gave it a whirl and it was absolutely fantastic. I could vent the bag when it got a little too warm and not completely expose myself to the air, and I never felt like I was sticking to the bag and allowed me move around inside my bag with little effort. All in all a great product. It did seem to me though that with a little experience with a sewing machine and some fabric you might make one a lot cheaper. cheers

Rated 5 out of 5 by from Lightweight and oh so fabulous Get the long, no matter what. I've had mine for several years. It wears well, washes well and dries quickly. Keeps my sleeping bag cleaner & gives options for warmer or colder weather. It's great on a cold plane, in tropical climates or skanky hostels and doubles as an anti-mosquito layer when desperate (yes, you can breathe through it). I am only 5'5" and when I want to pull it over my head, the regular is too short.

Rated 5 out of 5 by from So warm! Don't even need a sleeping bag I got this liner for a backpacking trip across Europe. I knew I wouldn't be showering very often so I got it to protect my sleeping bag from "the funk". Most of the time, I spent the night laying on top my sleeping bag inside the liner. Using just the liner, I was comfortable on nights getting down to 60 deg F. I am 6'2" and this seemed a little short on cooler nights.

Rated 5 out of 5 by from Should have bought this sooner. This made sleeping in my bag a more comfortable experience. I have an awesome bag - Nemo Salsa 30 degree, but I stick to it when I sleep or get tangled trying to roll over - my experience in other bags, too. This liner, allowed freedom of movement. The fabric didn't stick to me & felt good pulled up to my chin. It looks to be very delicate, but seems durable. I like that is a color & not white, so it won't show the dirt, as I am planning on it keeping my bag cleaner on those multi-day hikes, where you go to bed without a proper shower.

Rated 5 out of 5 by from Perfect for Hot Weather Travel On the recommendation of a sales associate, I bought this as a sleep sack for my son to use in Ithaca New York in August until his bedding arrived at his dorm. It turned out to be the perfect weight and texture for the heat and humidity (the cotton made it cooler than a purely silk liner). I packed this sleep sack with an REI back-packing towel and inflatable pillow into his suitcase. The whole set took up the space of a t-shirt and kept him comfortable and clean for as long as he needed it. Perfect hot weather travel bedding.

Rated 5 out of 5 by from Works well Good to have a longer version for us tall folk / hand washes easily - dries quickly / SO nice to be able to keep sleeping bag cleaner / sometimes, this old guy wishes it had a partial side opening

Rated 5 out of 5 by from Feels great, keeps bag clean, packs down light. I love this sleeping bag liner. I used it in a summer bag rated for down to 40 degrees. We had an unexpected cold front come through while out and it did get down to the forties one night. While I bought the liner for cleanliness I did find it added heat on that cooler night and I woke up much more rested than my counterparts who were without a liner. This liner also fits nicely back into the bag it comes in, a lot of times you can't get it back in no matter how hard you try, I folded one time and it slipped right in!

Rated 5 out of 5 by from Oh, so comfy! It made my somewhat cold-feeling nylon bag feel like my own fomfy bed at home.

Questions & Answers

For those with allergies & sensitive skin: Should this Sea to Summit Premium Blend Silk/Cotton liner be washed before sleeping in it? (Should the Silk Stretch Traveller Liner and/or the Cocoon Silk Bag liners be washed before sleeping in them?)

Asked by: redwhiteandblue
I'm a sensitive skin girl and wash EVERYTHING before wearing/using.

Does this have a zipper to make it into a double?

Asked by: ExiledMainer
The Premium Blend Silk/Cotton Liner does not have a zipper so two cannot be zipped together.

Would it be possible to cut this down one side to open it up and then hem the edges. I would like to fix it so that my feet fit into the tube but otherwise as a cover. Thanks

Asked by: Kawabungie
Yes, it is possible to open up the liner as you mentioned. This would void the warranty if you decide to return it.

Hi, does this liner have a side opening, where a sleeping bag zipper would be, or is it a tube with one end closed, like a pillow case? Thanks

Asked by: airplane to camping
No, the Premium Blend Silk/Cotton Liner​ does not have a side opening. It is simply open on one end, just like a pillow case, but for people.

I have the REI Lumen 20 mummy sleeping bag. Would you recommend against a rectangular shape liner such as this for use with a mummy sleeping bag?

Asked by: NewToCamping
​While you can use this rectangular liner with the Lumen 20 bag, a mummy shaped liner is going to be a better fit.

The common complaint seems to be that the mummy version is too constructive. at 6 3 260lbs I expect that to double. Why wouldn't the rectangle option solve this problem in a mummy bag?  Thank tou

Asked by: Bosoxrox
While a rectangular liner would fit in the mummy sleeping bag, the mummy sleeping bag does not offer enough room for the liner to relax; the liner will bunch up around the lower legs and create constriction.
