The Mammut Men's Alvier HS Pant easily transitions from snowy ski resorts to powdery backcountry. Gore Tex gives this thin three layer shell reliable waterproof breathable protection in snowfall, and the C Knit lining betters the pant's breathability, moisture management, and comfort on steep skins. Fully taped seams enhance waterproofing by preventing a single snowflake from seeping through. Mammut fixed the Alvier with full length side zippers to give ventilation and easy on and off with boots on. The bib is removable for groomer days, and a jacket to pant interface connects the Alvier to Mammut's compatible ski jackets for complete coverage. The cuffs feature Dyneema reinforcements and adjustments to keep the cuffs off parking lot pavement. Mammut designed the zippered bib pocket specifically for the Barryvox beacon.
