Keeping in mind those who redline in the alpine, our Nano-Air(R) Light Hoody represents another step forward. This light, stretchy, extended-range midlayer quickly became a tester and ambassador favorite due to its dynamic insulation and sweet-spot breathability. The fabric package sheds snow and maintains the same impressive stretch as our regular Nano-Air (100% stretch nylon shell and liner), but it's three-quarters more breathable and a third less insulative (using 40-g FullRange(R) 100% polyester stretch insulation)-meaning, you'll never need to take it off. The stripped-down, deep-venting pullover silhouette remains trim through the midsection, while the engineered pattern eliminates seams across the shoulders and back, thus removing abrasion points and enhancing comfort. The hood works alone, under a helmet or stretches over lower-profile helmets, and the polyester/spandex stretch-woven Variable Conditions Cuffs are shaped, patterned and seamed to reduce bulk when layered and allow easy push-up without constricting the forearms. With an exterior left-chest zippered pocket.
