Pre-owned in excellent condition! Wool insulation. Placing Lavalan (as the wool insulation is called) in strategic areas helps minimize weight by only applying it where necessary. The wool is naturally a little heavier than down or synthetic insulation, but not by much (the jacket is 1004 grams). Odor resistance, temperature regulation, and moisture management. Wool is naturally wicking and breathable and creates a natural microclimate within the jacket. This jacket is very effective and adds certain versatility that you wouldn't see in a chunky down jacket for example off with a BD Dry 20k/20k membrane and fully taped seams, plus pretty much all the standard features you'd expect, the Boundary Line Mapped has taken Black Diamond's big mountain ethos and applied it to a jacket that should appeal to the all-mountain masses and to free riders alike. *Jacket is built to keep you charging thru the bone-chilling days of the season. *Fully taped * 20,000mm waterproof 20,000 g/m2/24hr laminated B.D.dry waterproof/breathable shell fabric w/ mechanical stretch * Revolutionary, PFC-free GTT Breathable Water Protection DWR finish * 60g Thermolite synthetic insulation * Ski helmet-compatible hood * YKK Aquaguard zippered center front, hand, & chest pockets * Zippered sleeve pass pocket Internal zippered chest pocket * Internal mesh dump pocket Internal stretch powder skirt * Underarm zippered vents * Dual drawcord hem *Zippered sleeve pass pocket * Weight - approx. 1 lb, 11 oz
