Mont Helios Down Vest Men's

The Helios Vest is the result of years of design refinement with meticulous attention to detail.

Built for alpine climbing, technical mountaineering and remote alpine camps, it is engineered for high-altitude conditions where warmth, weather protection and freedom of movement are essential.

At its core is 900+ loft white goose down in a box-walled construction for maximum thermal efficiency, protected by PFAS-free Hydronaute XT, Mont’s most breathable and weather-resistant shell fabric. Inside, a recycled nylon ripstop lining with XReflex™ radiant barrier technology reflects body heat back to the wearer, enhancing warmth without adding weight.

With complete freedom of arm movement, the Helios Vest provides uncompromising core warmth without unnecessary bulk, making it equally effective layered under a shell or worn alone in milder alpine weather.

From bitter wind chills to exposed ridgelines, the Helios Vest is tough enough for the most demanding environments and refined for precision in technical terrain.
