What Our Gearhead® Experts Are Saying:“I’ve taken the Broad Peak on ski tours, ice climbs, and cold alpine starts—its warmth-to-weight ratio is unbeatable. It compresses small in the pack, layers over a shell perfectly, and the zip pockets are accessible with a harness.”We count on the Broad Peak IN Hooded Jacket from Mammut when temps drop and the summit is still hours away. This updated alpine essential delivers the premium warmth of 800-fill down in an ultralight package that stashes small in our pack but makes a big impact when we need it most. Whether we’re ticking off winter routes or skinning into the backcountry, the Broad Peak traps heat without weighing us down. Engineered with Pertex® Quantum fabric for windproof durability, this down jacket features a two-way front zip for easy harness compatibility and ventilation. A drawcord hem adjusts one-handed, elastic cuffs seal out drafts, and climbing-specific pocket placement ensures access while roped up. Plus, the entire jacket packs into its side pocket, making it a reliable midlayer or emergency insulator on technical missions. Lightweight, compressible, and responsibly made, it’s everything we want from our alpine insulation.
