Morning's chilly enough to get your teeth chattering, but you know the day is sure to heat up. That's when you'll be glad to toss on the featherweight, packable warmth of our Down Shirt Jac. Its 650-fill down insulation holds in body heat without bogging you down. A light-yet-strong 1.5-oz. polyester shell sheds mist and sleet, keeping you dry in a sudden shower. Armpit Gussets let you reach up without it riding up – no exposing bare skin to the elements or prying eyes. Snap front, pockets, cuffs open easy, even with cold-stiff fingers.
