Montbell Warm-up Sheet. This is a brushed sheet designed to increase the warmth inside a sleeping bag. It's lightweight and can be stored compactly. Convenient for tent camping as well as staying in mountain huts. I purchased this over 10 years ago and used it a few times. After that, it was stored in a closet for a long time. Please understand this before purchasing.
