The Mammut Stoney HS Thermo Jacket for Women offers the perfect balance of weather protection and insulation, which helps keep you dry and warm on any and all of your ski adventures. The Stoney is insulated with Ajungilak OTI Element synthetic insulation (80 g in body and 60 g in arms and collar) adds lightweight warmth and continues to insulate even if it gets damp. A 2 -layer Mammut DRYtechnology Pro material offers 20,000 mm/20,000 grams of waterproof/breathable protection that keeps you dry even in the heaviest of snow storms, sleet, or rain events. With an adjustable, detachable hood that fits over a ski helmet, you add critical head protection to keep you warm and comfortable. A waterproof AquaGuard zipper on the front of the jacket and all of the outside pockets helps keep things nice and dry too. When you are working hard on that boot pack to get above tree line for those classic side-country ascents, large pit zips help dump heat and keep you cool and comfortable. A removable powder skirt helps keep the snow out on those ultra-deep days when you are skiing from first chair to last. There is truly no better crossover jacket for resort laps or skinning in the backcountry than the Mammut Stoney HS Thermo Jacket for Women.
