    Crashed in my hammock under tarp, during a rain and hailstorm with temps dipping into the low 30s. Bag was a bit damp on the outside but nice and dry on the inside. Lucked out with blue skies and sunshine the next morning and the dampness was gone within minutes. The central zip is great, especially for a hammock. The only reason for 4 stars and not 5 is the footbed stow away operation. The toggles and loops are a bit small and get lost in a pillowy bag when fumbling around in the dark. Definitely not a deal breaker. No disappointments with this bag so far.

    Love this bag. I wanted something small and packable but still warm for when I have to fly with my camping gear. Traditional mummy bags have invariably resulted in bad sleep for me as I sleep on my side and end up tangled and uncomfortable. Not so with the mobile mummy! I was skeptical about the dorkiness factor, and am still not sure how often I'll actually wear it outside the tent as designed, but it's comfortable, warm, and most importantly rolls with me when I sleep. I like being able to stick my arms out to read too. I'm a woman but got the men's bag because I'm 5'9" and I generally find women's bags too short. I don't notice any difference/problem with the men's shape, and I don't have particularly small hips. The hood is snug and warm without requiring toggles for tightening that rub against your face. I can't think of any drawbacks to this bag except maybe the price, but for down and compared to the MSRP the deal on STP was a steal. Very happy customer!

    Light, and packs small, good for backpacking. Slept in the low 30s/high 20's with shorts and long fleece t-shirt, no need for hat.

    Con: Stuff sack, very basic w/o compression straps, it packs way smaller.

  • “Is the shell water resistant?

    How is it having the zipper in the front instead of on the side? Does it touch your face?”
    Asked by Tay tromping through timber from Utah on 7/13/2017 7:11:08 PM
    • The shell is not listed as water resistant.

      The zipper does not touch your skin, it is protected by a fabric guard along the body and a zipper garage at the top.

  • “Is this bag specifically for men, or would it work for well for medium sized female? I'm 5'7", 129 lbs...”
    Asked by Meli from Colroado on 5/2/2017 9:35:47 PM
    • Not sure, but bag is roomy enough. I'm 5.5 and 180 and it fits well. Worst case send it back, it's a great bag.
