About this product

The Helios Pants are a great addition to your pack for alpine ascents or ski touring. Full length separating side zips allow you to quickly put them on in the field without having to step out of your skis or remove your boots and crampons, a crucial feature on steep slopes and in frigid conditions. Packed with premium 900+ fill power goose down, the Helios Pants are a cozy treat at the end of a long day and a necessity in cold conditions. 

We recommend sizing up a full size for down pants if you plan to wear over any layers.

Ideal for: ski touring, winter camping, winter in Fairbanks, cold mountaineering
