The Arc'teryx men's Trino Tights are designed for guys who live for those days they can run steeper trails 5 kilometers longer than their regular tracks. These tights have leg-fronts constructed with GORE WINDSTOPPER, which is windproof, water-resistant, and breathable. Their backings are made of air permeable fabrics that provide comfortable thermal performance and are treated with a water-repellent DWR finish. The Trino's come in an articulated fit for enhanced mobility and feature flatlock seam construction to reduce internal chafing. The waist has an adjustable drawcord. Gusseted 9" zippers at the ankles deliver a superior lower-leg fit.
