"What Our Gearhead® Experts Are Saying:""I have been using the Broad Peak Light IN as my go-to belay jacket on ski tours and alpine routes where every gram in the pack matters. The micro-baffle construction keeps the down evenly distributed so there are no cold spots when I stop moving, and the fact that it stuffs into its own pocket means I can clip it to my harness or bury it at the top of my pack without any extra bulk.""Fast and light objectives demand gear that earns its weight, and the Mammut Broad Peak Light IN Hooded Jacket is one of those rare pieces that justifies every gram it asks you to carry. At just 238 grams, it disappears into a pack during the approach and reappears the moment you stop moving and need warmth fast. The micro-baffle construction keeps 800-fill DRY DOWN evenly distributed across the jacket, eliminating cold spots while keeping the silhouette trim and close to the body for easy layering under a shell. The DRY DOWN treatment helps the insulation retain warmth even when exposed to moisture, which makes a real difference on multi-day routes where conditions are rarely perfect. A pre-adjusted low-profile hood pulls cleanly under a helmet without readjustment, elastic cuffs and hem seal in heat at the edges, and backpack-compatible zippered pockets stay accessible even when shoulder straps are cinched tight. The whole jacket packs into its own front right pocket for fast transitions at the top of a pitch or the base of a skin track. Built from recycled polyamide throughout and Bluesign approved, the Broad Peak Light IN is a precise, purposeful layer for anyone moving fast in the mountains."
