As soon as you put the Diablo Down Jacket on, you won't want to take it off. Stuffed with 700-fill of recycled insulating down, it delivers welcome warmth with lightning speed. And elasticated cuffs and an adjustable hem lock in body heat. It's pretty hardy too, thanks to the woven polyester fabric. Layer it over a shell when taking a well-earned rest or wear it over a midlayer on dry but cold days.
