Slept in it down to 25 degrees in Pisgah Nat'l Forest and was snug as a bug. The hand pockets are amazing.... Packs down to the size of a large grapefruit. As a side sleeper, the mummy bag was always restrictive. This has changed everything. I do think that an insulated sleeping pad is a must have accessory to the quilt though.
