Mammut Alto Guide HS Hooded Jacket

The Mammut Alto Guide HS Hooded Jacket is a technical 3-layer hardshell built for mountain travelers who demand reliable protection in demanding environments. Constructed with Mammut's DRY Tour laminate, it seals out wind and moisture while maintaining breathability for high-output days in the alpine.

With a 20,000 mm waterproof rating and 20,000 g/m²/24h breathability, this jacket keeps you dry during sudden downpours and intense ascents. The PFC-free DWR treatment sheds rain and snow, while underarm ventilation zips offer rapid heat dumping when the pace rises. The helmet-compatible hood, pre-shaped sleeves, and Velcro cuffs provide a secure, adjustable fit, and pockets are positioned to work with a climbing harness.
