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