What Our Gearhead® Experts Are Saying: "This is one of my favorite active layers year-round. It breathes incredibly well on the move, dries fast after hard efforts, and layers cleanly under a shell. The hood fits under a helmet without bulk, which makes it great for alpine and climbing days." We rely on the Lumiko Hooded Jacket when movement, breathability, and versatility matter most. Built by Mountain Equipment as a lightweight stretch fleece, this layer delivers excellent warmth for its weight while staying comfortable through high-output days in the mountains. The ribbed fleece construction keeps bulk low while trapping warmth, and the highly wicking fabric manages moisture efficiently during long climbs or steep approaches. A low-profile hood adds just enough protection from wind or sun and fits neatly under a helmet, while the active fit and stretch allow unrestricted movement on technical terrain. From trekking and hill walking to alpine climbing and ski touring, this is a layer we reach for again and again.
