What Our Gearhead(R) Experts Are Saying: "I like the Stoney HS Thermo because it blends full storm protection with just the right amount of insulation. The DRYtechnology Pro shell really holds up on wet, snowy days, and the Ajungilak insulation keeps me warm without overheating. The underarm vents are clutch when I'm booting up to find untracked lines."When we're chasing powder through stormy days, the Mammut Stoney HS Thermo Hooded Jacket gives us the protection and warmth we count on. Mammut built it with a DRYtechnology Pro 2-layer membrane for reliable waterproofing and breathability, so we can ski bell-to-bell without worrying about getting soaked. Fully sealed seams keep snow out, while Ajungilak OTI Element insulation delivers balanced warmth in the body, sleeves, and collar for cold chairlift rides and windy ridgelines. This jacket adapts when we need it to. Zippered underarm vents open up airflow for hikes to secret stashes, while the adjustable, removable hood lets us fine-tune coverage for storm days or style. A smart pocket layout-including chest, hand, and sleeve options-keeps essentials like snacks, passes, and liners organized. The Stoney HS Thermo is a hardworking insulated shell built for skiers and riders who won't let winter conditions slow them down.
