Avery's roll-style Fleece Hand Warmer is a terrific value! Soft 13-oz. camo spun poly fleece on the exterior is layered against 9-oz. black fleece on the interior with 100 grams of Thinsulate insulation in the middle for extra warmth. Plenty of room for even the biggest hands, and the belt will expand to 60". Large front zippered pocket to hold heat packs, keys, bullets, etc.
