Using 100% recycled synthetic FireLine ECO insulation, this bag maintains a low weight and amazing packability so that it doesn't take up too much space in your pack. It also uses the Big Agnes Flex Pad Sleeve to easily attach to sleeping pads, creating a comfortable sleep system that helps maximize your rest at camp. It even uses comforter-style lining to give you some extra space inside the sleeping bag without sacrificing the thermal efficiency of traditional mummy bags.
