User Review: Sierra Designs Nitro 15
This thing was quite an upgrade over my REI Polar Pod +20. After spending many nights not-quite-warm-enough in my Polar Pod, I decided to spend a bit more and get something better. I am really impressed by the light weight, small packed size, and fill of the bag. I've been warm every night I've slept in it.
