    Comments about Cosmic 35 Sleeping Bag (Synthetic):

    I was looking for a three season bag I coud use on the odd cold night that packed small and was lightweight. As an older hkier weight is a major concern. The zipper on the bag slid easily without snagging and felt good. I am 5'10" with a 57" shoulder girth and the bag felt roomy compared to others I've tried. The 35 F rating is definitely survival limits. I'll add a silk liner to improve the warmth a couple of degrees. Overall, I think I found what I was looking for. Hopefully I'll see how it holds up on the AT next year or at least some 100 milers locally. I must also note pack size and weight appear to be as advertised. My reg is 8"x14" packed and shy of 3lbs on my bathroom scale. I also managed to roll the bag while standing and stuff it in the storage bag. without too much difficulty.
