Snugpak Silk Sleeping Bag Liner with Stuff Sack, Heat Management for Hot or Cold Climates, Black

This sleeping bag liner helps trap and retain heat when it is closed to ensure you stay warm in cold weather. In hot climates, sleep with the liner open to release heat and allow a breeze to pass through and cool you down. Made with a heat managing silk and cotton blend; liner dimensions are 87 inches long by 31 inches wide. To prevent the liner from twisting within a Snugpak sleeping bag, secure the liner using the tie in loops near the feet to attach them together. Lightweight; weighs 5 ounces and includes a stuff sack so you can pack the liner down to a travel-friendly 6 by 3 inches
