When a day starts cold and stays cold, the Jack-ZZ Down Jacket holds its warmth with 800-fill recycled down. The hood's adjustable drawcord storm visor shields the face from the weather, while elastic cuffs and an adjustable drawcord hem close off the openings where heat escapes. The shell is water-resistant and repellent, so light moisture sheds before it settles in. What Our Gearhead(R) Experts Are Saying:"Walking a city for hours, up and down stairs and across crowded crossings, the two-way stretch shell moves with every stride and arm swing. When I stop to check a map or wait at a light, the down holds my warmth."
