"What Our Gearhead® Experts Are Saying:""This jacket is a powerhouse for cold belays and winter alpine routes. The thick insulation and helmet-compatible hood keep me warm while standing still, and it packs surprisingly small for how much warmth it provides.""The Rime Pro Belay IN Hooded Jacket is our trusted shield for frigid belays and wind-whipped ridge lines. Mammut designed this technical piece with serious mountain pursuits in mind, dialing in insulation, durability, and utility in a relaxed-fitting, layer-friendly silhouette. Stuffed with 140g of Mammut's LOOPINSULATION—plus an extra 80g in the hood—this belay jacket delivers serious warmth without the bulk. The climbing-helmet-compatible hood, adjustable hem, and elastic cuffs help seal in heat when we're on standby or exposed to whipping wind. Recycled materials and a PFC-free DWR offer eco-conscious protection, while PowerMesh internal pockets and a packable design ensure it earns its spot in our alpine kit."
