For active comfort when cross-country skiing, we throw on the Swix Infinity Hybrid Wind Full-Zip Pant. This windproof, water-repellent pant is optimized for getting after it in cold weather, slicing through strong headwinds, deflecting flurries, and allowing high levels of breathability thanks to its thin mesh lining. The elastic waist and semi-fitted design make the Infinity well-suited for cross-country skiing, but also keep us comfy on hiking and training days. Stretchy, ventilating panels keep us moving freely while pushing internal moisture out, and reflective details boost our visibility in low-light conditions when the day gets away from us.
