Jackie M.wrote a review of Cocoon Silk Mummy Liner on March 11, 2013
Climbed to the top of Mt. Kilimanjaro with this liner in my down sleeping bag. I was plenty warm during the very cold nights on the mountain. The liner is slippery so I never got tangled up in it. There's no Velcro to caue any rough spots and it felt even better against my skin then the inside of my sleeping bag usually does. And it's a lot easier to wash than my bag is. I'll take it whenever I camp from now on.
