Adding an additional 9.5 degrees (Fahrenheit) of warmth and increasing the longevity of your sleeping bag, the Cocoon MummyLiner Silk is a tapered bag liner. On balmy nights, the fast-drying, lightweight MummyLiner Silk may be all the coverage you need.

Each MummyLiner Silk includes its own integrated drawstring hood, a boxed foot-end and durable double-stitching.

Great liner!
Reviewed by Oldranger - July 6, 2017

Likes: Works great for keeping the inside of sleeping bag cleaner and also works great by itself for hot summer Texas nights. Very easy to slip in and out.

Dislikes: None

Great liner
Reviewed by Chris H. - January 18, 2017

Likes: Light weight, warm, comfortable

Dislikes: No zipper makes getting in and out a bit difficult but not terrible.

Overall good product...if you are 8 feet tall.

Likes: I got this to serve a dual purpose, to keep my down bag clean and to allow me to unzip my bag when it was warm and still have a cover. It works for that, but it is HUGE! It is a one-size fits all, and they mean fits a giant. While it packs small and is fairly lightweight, I really don't need all that extra cloth when I am backpacking. Guess I should have read the dimensions closer. I plan to cut it down if I can find someone whose sewing machine handles silk. It also doesn't open on the side at all, so you have to crawl into the top of it. Not very convenient. On the plus side, it does feel nice against the skin.

Dislikes: Way too big and too much cloth.
No side opening.

Likes: I used this liner in my 20-degree sleeping bag while camping in the Smoky Mountains last weekend. It added that extra bit of warmth on the cold, snowy nights and I didn't even notice it was there. Great addition for winter camping! Looking forward to using it as a basic sheet for hot summer camping.

Dislikes: Not a thing!

Reviewed by Inside Edge Member - December 2, 2014

Likes: Functions as advertised. Can't really tell if it adds 9.5 degrees to my bag but it certainly makes it quite a bit warmer than it was before. Super soft feel for ultimate next to skin comfort. Easy to take out and wash. Packs down to a grapefruit size easily and has a great carrying case. Also seems pretty durable, but I've only used it once.

Dislikes: Get's dirty easily but washes easily so not a big deal.

Reviewed by Anonymous Backcountry Edge Customer - July 1, 2014

Likes: This definitely keeps me warm on cool nights. Adds a little extra warmth while not clinging to the skin like some synthetic liners of mine have in the past.

Dislikes: No complaints!

Reviewed by Anonymous Backcountry Edge Customer - June 16, 2014

Likes: Like having silk sheets to sleep in. Saves on washing the bag itself - just wash the liner. Have not used it much but seems like quality and will last.

Dislikes: have not used it enough to say whether there is anything I did not like

Reviewed by Mike B. - May 14, 2014

Likes: This lightweight liner went a long way in keeping my bag clean on and extended hiking trip. I got pretty funky after 6 days, but all it took was throwing the liner in the wash to freshen things up again. It also seemed to add 5-7 degrees of warmth on several of the colder nights.

Dislikes: The only negative would be the drawstring on the top. It kept getting caught in the zipper of my sleeping bag so I cut it off. Other than that I'm very satisfied with this liner.
