Weather a cold spring, an early frost, or a mild winter: 700-fill goose down insulates in cold weather, while the waterproof and vapor permeable Pertex Endurance shell keeps this bag dry in damp tents or dripping snow caves. Patented, welded-baffle construction prevents needle holes in the shell, retaining the waterproof performance of the fabric. A side baffle prevents the down from shifting to the bottom of the bag on long, chilly nights and an external storm flap protects the zipper from precipitation. Baffles are attached to the ripstop polyester interior using tuck-stitch construction for greater durability. The full-length zipper allows a wide-range of ventilation options and allows the Ibis to mate with other sleeping bags. An inner pocket with a hook and loop closure is ideal for storing an alarm or a headlamp within easy reach. 700-fill goose down insulation, maximum insulation Waterproof/vapor permeable Pertex Endurance nylon shell; ripstop polyester lining Patented Exped welded-baffle construction External storm flap protects zipper from moisture entry Tuck-stitch construction on lining Tricot side baffle prevents down shift Full-length zipper vents and connects with other bags Inner pocket for small item storage No-see-um netting storage sack Avg. weight: M: 44 oz./1240 g; L: 48 oz./1350 g Temp. rating (comfort/extreme): F: 18/9; C: -8/-13
