The Mammut Men's Alvier HS Hooded Jacket protects you from powder whether you're ski touring or freeriding. Gore Tex gives this thin three layer shell reliable waterproof breathable protection in snowy conditions, and the C Knit backer enhances 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 unique underarm vents that zip down the entire sleeves in order to convert the jacket into a vest. The powder skirt removes for groomer days, and the helmet compatible hood uses three way adjustments for secure coverage in windy weather. There are Lycra hand gaiters with thumbholes, hook and loop tabs on each cuff, and a jacket to pant interface for complete coverage from the cold.
