Engineered for alpine versatility, the Broad Peak IN Hooded Jacket is built to perform through shifting conditions—from cold summit pushes to windy belay stances and crisp shoulder-season hikes. Designed for women who move confidently through the mountains, this jacket blends lightweight warmth, sustainable materials, and reliable protection in a compact, durable design.
At its core, premium 800 cuin fill-power Nikwax Hydrophobic Down provides exceptional loft and heat retention without excess bulk. Unlike untreated down, it stays warm even after days of exposure to moisture—thanks to its PFC-free, water-based hydrophobic treatment, which maintains insulation and loft in damp or variable conditions.
The exterior uses Pertex® Quantum, a soft yet abrasion-resistant fabric woven from 100% recycled nylon yarns. Its tightly woven structure maximizes the thermal efficiency of the down, sealing in warmth while repelling wind and light precipitation. Combined with a PFC-free DWR finish, it ensures dependable protection against the elements while maintaining breathability on the move.
Thoughtful details refine its performance in the alpine environment:
An elastic, low-profile hood that seals in warmth without restricting movement or visibility.
Two backpack- and harness-compatible hand pockets and a zippered chest pocket for essentials you need within reach.
A two-way YKK Vislon® zipper for smooth venting or belay access.
Elastic cuffs and a single-pull adjustable hem that can be cinched one-handed to block drafts.
When the temperature rises, the entire jacket packs neatly into its own pocket—compact and ready to stow in a pack or clip to a harness.
Every component reflects Mammut’s long-standing commitment to responsible, high-quality craftsmanship. The down is RDS-certified and fully traceable, ensuring it comes from well-treated animals, while Fair Wear certification guarantees the garment was produced under safe and fair working conditions.
From technical ascents to daily winter wear, the Broad Peak IN offers reliable warmth, intelligent design, and sustainable construction—proof that mountain performance doesn’t have to compromise environmental responsibility.
