Worn a few times skiing but they are too large for me. Gently worn, just washed. Great base layer from backcountry. 74% wool, 19% polyamide, 7% spandex. I love how much wool is in these and they have great stretch. Wish I’d gone for a different size at the time! Style description: We built the Flagstaff Merino Bottoms to cater to the indecisive winter sports enthusiast, who can be found participating in any given activity. This wool baselayer features ventilated panels for high output activities like Nordic skating, snowshoeing in Grizzly Gulch, or trail running between seasons. Thanks to the secure-fitting elastic waistband and athletic cut, these bottoms are also great for more dynamic disciplines like ski touring or fat-biking.
