Core warmth with feather weight and synthetic performance defines our Micro Puff Vest. It delivers the best attributes of down and synthetics with a revolutionary insulation that has an unprecedented warmth-to-weight ratio. The groundbreaking PlumaFill insulation (65-g 100% polyester) is phenomenally light and compressible; offering the feel and warmth of down that still traps your heat when it's wet. A nylon ripstop Pertex Quantum shell, with a DWR (durable waterproof repellent) finish, blocks wind and snow. The garment's streamlined design maximizes performance and minimizes useless fluff. Features: zippered handwarmer pockets (the left pocket doubles as a stuffsack with a reinforced carabiner clip-in loop), a pair of sleek internal drop-in pockets (made without excess, using the backside of the handwarmer pocket bags) and elasticized hem.
