Mammut Stoney HS Thermo Pants

The Stoney HS Thermo pants combine synthetic insulation with a regular ski fit. Side vents and reinforced lower legs make them a practical option for resort skiing when you want warmth built into the pants.

Product guide · Manufacturer specifications

For colder chairlift days

These are insulated waist pants, not a shell or bib. A base layer still matters, but the filling supplies additional warmth during lift rides and time spent standing around.

Mammut offers short, regular and long lengths for this model. Try the length over your ski boots so the cuffs cover them without dragging or bunching.

Protection around the boots

The DRY Tour fabric has a 75-denier outer and a 15,000 mm waterproof rating. Cordura reinforcement protects the lower edges from wear around ski boots and ski edges.

Integrated gaiters use a nonslip grip to sit around the boots. The reinforcement and gaiters do different jobs: one protects the pants from abrasion, while the other helps keep loose snow out.

Vents, fit and pockets

Two-way side zippers let you adjust the ventilation opening when you get warm. This is useful on active runs, but for long climbs or warm spring days an uninsulated pair gives you more control over how much warmth you wear.

The waistband adjusts from the outside. Two front pockets have water-repellent zippers, with pleats to create more room inside. The regular cut keeps the design closer to conventional ski pants than a loose snowboard-style bib.
