- Familiarity: I've used it several times
I hate the restrictive feeling of a mummy bag and this is a perfect solution! I can tell you Sea to Summit is pure quality!!! It seems true to its temperature rating, and I have never gotten cold (slept comfortably when it was in the low twenties). Finally a zipper that doesn't snag!!! I feel like this bag will last me a long time and am super happy with it.
