    1. Nitro 800 womens

      This bag worked great. First time out we were in the Sierra's and the temps were in the low thirtys. First night I slept in a tank top and pajama pants and was comfortable but not overly warm. The second night it had rained and hailed so I added my down sweater and was toasty warm all night. Others were wearing multiple layers. I am always cold so this bag was a big improvement over my 10 degree and I only increased my weight by 1 ounce. Love the bag. on Jun 6th 2018

    2. Actually kept me warm!

      This was an upgrade form a 30degree bag and it was phenomenal. Our temps got down to mid 20s and I was warm, which is surprising. I am always cold and my feet are usually the hardest to keep warm. I was concerned they feet vent would let in cold air, but I can attest that my feet stayed warm at temps around 25!

      Shipping was fast which was great, as we needed for the weekend too.

      Definitely would buy again and recommend.
