MammutAlvier HS Hooded Jacket - Men's

The deeper the powder, the sweatier the skin.

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.

Great Jacket - One Big Flaw

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Large

Bought this jacket for freeride and side country skiing. Great jacket with all the needed features (water proof, breathable, goggle cloth, sleeve pass pocket, pit zips, and external and internal pockets). The big flaw is that the hood is not truly helmet compatible; it comes part way over my helmet (medium size helmet) and the front zip cannot be zipped all the way. It is advertised as helmet compatible, but try before you buy. On those blowing, snowing, powder days when you want to hunker down on the lift or at the top of a slope it doesn't work.

Great Ski Jacket

This is a great ski jacket with features you use when on the mountain. I am a fan of Gore Tex for my ski gear which this is. This kept me dry all season even through the pineapple express storms.
