Flylow Puffer Pant Women'sIt was a chilly storm day at the resort and a skier was wearing traditional long underwear bottoms and she was cold. Her friend, on the other hand, was sporting the Puffer Pant, soft fleecy long johns with insulated panels above the knee. She was warm enough to stay out longer. Flylow's point: Insulated long underwear has a place in this world. Plus, the Puffers are cozy enough to double as sweats around the cabin. Material Furano Fleece: 94%
