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.
