Built to keep backcountry skiers and riders dry on the sweaty uptrack and warm on the chilled descent, the Boys's Capilene 2 Lightweight Bottoms from Patagonia balances fast-drying performance with lightweight insulation. Made with an open-knit 4-oz 100% polyester (54% recycled) that provides exceptional breathability, wicks perspiration, and dries in a flash, these bottoms are the ultimate in comfort beneath layers on chilly days. They feature a brushed elastic waistband for softness, a gusseted crotch for unrestrained motion and side seams set forward to eliminate chafe. With a effective fly and Gladiodor odor control for the garment. Recyclable through the Common Threads Recycling Program.
