I bought this blanket for a summer outdoor-sleeping blanket/light-weight backpacking blanket/and part of a modular sleep system for cold weather. So far I have only used it as a summer outdoor sleeping blanket, and I absolutely love it as that! This is my first light-weight down blanket, although I’ve used heavier down comforters for years during the winter. I like to sleep outside and this blanket is great for that! It’s so light weight I barely feel it, unlike the thin wool blanket I had been using. And by covering or uncovering I can stay completely comfortable when the temperatures fluctuate.
