The MontBell Plasma 1000 Down Jacket represents the ultimate in minimalist, ultralight design. No pockets, no hood, no bells and whistles. Only serious warmth in a super light and extremely packable package. Unheard-of 1000-fill powder goose down with a sewn-through construction provides extreme warmth, and the seven-dernier Ballistic Airlight nylon uses hollow fibers for insane weight savings. A DWR treatment repels water, and elastic cuffs seal out drafts. The jacket is cut trim to work well with outer layers. Everything about this jacket is designed with the weight-conscious winter athlete in mind, and as an added bonus included with purchase is a stuff sack for easy packing.
