Built for layering during a cold, snowy winter adventure, the Backcountry Waas Allied Down Short brings added warmth and comfort to our day at the resort, winter hike, and whatever else may require staying warm. These 800 - fill Allied down - insulated shorts are easy to layer on top of a baselayer and under ski pants and — thanks to the fully separating side zippers and packable pocket — are even easier to shed and stash in a pack if we get too hot. For a personalized fit with optimal mobility, we added an elastic waist with a drawcord for easy adjustments and performance knit panels and gusset.
