La Sportiva N.A. Men's Trango Trek GTX Hiking Boot
Made from recycled materials, these weather-defying hard shells pair abrasion-resistance with a motion-enhancing design. Powder Bowls have a tough, 2.5-layer canvas shell (made from 100% recycled polyester), and block weather and snow with a waterproof/breathable H2No® barrier and a Deluge DWR® (durable water repellent) finish. Lined through the seat and thighs with brushed mesh for extra insulation and efficient wicking; lower legs are lined with slick mesh (100% recycled) for glide. Articulated knees and a gusseted crotch allow legs to move through the full range of motion. Pocket rundown: two handwarmers (men's only), two thigh pockets and one rear pocket. The women's version has a feminine fit. Recyclable through the Common Threads Recycling Program.
