"What Our Gearhead® Experts Are Saying:""I love the Massone ML for chilly days at the crag—it has just enough warmth, doesn’t restrict movement, and the helmet-compatible hood is perfect when temps drop. It’s breathable enough for long approaches but tough where it counts.""We built the Massone ML Hooded Jacket into our climbing kit for cool-weather crag days and breezy summit pushes. Designed by Mammut specifically for rock climbing and bouldering, this midlayer balances breathable warmth with rugged durability in all the right places. Whether we’re roping up on crisp mornings or chasing shade in desert canyons, the Massone moves with us through every reach, mantle, and belay. A hybrid fabric construction blends stretch, softness, and abrasion resistance. The double-woven material on the elbows and front panels stands up to granite and limestone alike, while high-reach gussets and raglan sleeves make dynamic movement feel unrestricted. A close-fitting hood slips easily under a helmet, and the harness-compatible pockets are placed exactly where we need them. Built for vertical pursuits, this layer is one we reach for all season long."
