A fully functional fly adds everyday convenience, while the elasticized waistband adapts to your body for a secure yet flexible fit. 88% Merino wool, 12% recycled nylon. Machine washable. Imported. If you're not fully satisfied with your purchase, you are welcome to return any unworn, unwashed items in the original packaging with tags and if applicable, the protective adhesive strip intact.

Bought these for BC skiing and ended up using them for nearly everything short of summer heat. comfy, consistent size, and much warmer when wet/ sweaty than others I've tried. Note that these are the high merino wool percentage version.
