The Flylow Charlie Coat features the versatility we need to maintain an optimal body temperature when we're skiing or snowboarding in cold weather. The jacket is insulated with 700-fill down to provide premium warmth without the weight. At the same time, it features extra-long underarm vents to dump heat in a hurry when we're doing high-intensity activities that spike our body temperature and produce sweat. The Charlie Coat is fully waterproof and breathable, protecting our body—and the down— from the elements while releasing steam vapor to keep us from overheating when we're sending it.
