Montbell Warm-up Sheet. This is a brushed sheet that increases the heat retention inside a sleeping bag. It is lightweight and can be stored compactly. It is convenient for tent stays as well as hut stays. I purchased it over 10 years ago and used it several times. After that, it was stored in a closet for a long time. Please understand this before purchasing.
