The Snugpak Fleece Liner enhances your sleeping bag’s thermal retention properties for maximum warmth. The Fleece Liner is constructed with a lush knitted 100% polyester fleece; the fabric is brushed and sheared to provide the durable plush finish. The liner is equipped with a hood section that fits inside sleeping bags with draft collars and hoods. The liner hood is adjustable with a draw cord so you can customize the liner’s fit around your head to keep out the cold. The Fleece Liner’s dimensions are 94 inches long by 30 inches wide to offer you plenty of room while you sleep. The liner weighs 2.06 pounds and packs down to a travel-friendly 10 inch by 7 inch size within the included compression stuff sack. To prevent the liner from twisting within a Snugpak sleeping bag, secure the liner using the Tie In Loops near the feet to attach the two together. The Fleece Liner also features a full-length side zipper and is machine washable. The Fleece Liner will add another season of use to your sleeping bag’s comfortable use range so you can enjoy outdoor adventures year round.
