Completely redesigned, the Stoney HS is one of the most versatile insulated ski jackets in the Mammut range. Its waterproof 2-layer Mammut DRY Tour laminate provides reliable protection against snow and wind, while maintaining good breathability for prolonged exertion. With a water column of 15,000 mm and a robust construction made from recycled polyester, it perfectly meets the demands of alpine skiing and occasional freeriding.

A masterful balance between warmth and breathability

The Mammut Stoney HS jacket uses targeted synthetic insulation to provide optimal comfort without overheating. The recycled Ajungilak® OTI™ Element filling (80 g/m²) provides the necessary warmth on cold days, while the X-Vented ventilation zippers under the arms allow you to effectively regulate your temperature when the intensity increases. The result: you stay warm on the lifts and comfortable during exertion.

Features designed for skiing and freeriding

Designed for active use, the Stoney HS incorporates functional details that make life easier on the slopes. Every element has been designed for practicality and freedom of movement:

• Hood compatible with a helmet, easily adjustable
• Two-way YKK VISLON® zipper, waterproof and easy to use with gloves
• Underarm vents for quick ventilation adjustment
• Elastic, removable snow skirt for adjustable protection
• Multiple zippered pockets, inside and outside, to keep your essentials close at hand

A more responsible Mammut ski jacket

In addition to its technical performance, the Stoney HS is part of a strong environmental commitment. Its main fabric is entirely recycled and made from a single material, making it easier to recycle the jacket at the end of its life. Bluesign® PRODUCT certified, with a PFC-free water-repellent treatment and manufactured in accordance with Fair Wear standards, it combines technical performance, durability, and a commitment to sustainability, without compromising on the pleasure of skiing.
