Lightweight 2.5-Layer Weather Protection Engineered for Unpredictable Alpine Ascents

The Mammut Women's Crag HS Hooded Jacket is a technical, highly packable waterproof hardshell engineered to protect mountaineers, backpackers, and alpine climbers from sudden, punishing mountain storms. Constructed with Mammut's proprietary DRY Tour 2.5-layer laminate membrane and treated with a premium Durable Water Repellent (DWR) finish, this high-performance shell provides absolute windproof and waterproof integrity while maintaining excellent internal vapor transmission. Weighing well under 400 grams, its lightweight matrix folds down tightly into tight pack corners, serving as the ultimate low-bulk defensive layer for high-altitude singletrack and vertical routes.

Tailored specifically to meet the ergonomic demands of technical vertical movement, the jacket features fully articulated sleeves that prevent the hem from riding up while reaching for distant holds or planting trekking poles. The integrated, stormproof hood is fully helmet-compatible and features a multi-point adjustment system that preserves your peripheral field of vision during heavy downpours. To effectively regulate your core temperature on grueling, high-output climbs, the shell is equipped with two-way underarm pit zippers for instant, high-airflow ventilation, alongside two high-set, spacious zippered hand pockets positioned to remain completely accessible while wearing a climbing harness or a heavy backpack waist belt.

Key Features:

• DRY Tour 2.5L Membrane: High-performance waterproof and windproof laminate delivers reliable storm defense and high breathability.
• Helmet-Compatible Storm Hood: Deep, structured hood architecture shields the face and neck, adjusting precisely to fit securely over climbing helmets.
• High-Airflow Pit Zippers: Integrated two-way underarm ventilation zips allow you to dump core body heat quickly on steep uphill climbs.
• Harness-Compatible Pockets: Two large front zip pockets are strategically elevated to clear pack hip belts and climbing gear loops.
• Ergonomic Articulated Sleeves: Pre-shaped arm geometry ensures absolute upper-body mobility and stops the jacket from pulling out of place.
• Water-Repellent Front Zipper: Heavy-duty, matte-finished center zipper features an internal storm flap to seal out driving rain and sleet.
• Customizable Protective Fit: Outfitted with low-profile hook-and-loop cuff tabs and a one-handed adjustable hem drawcord to lock out freezing drafts.
