The Ferrosi Gaiter features hybrid-mapped Ferrosi and ActiveIce™, two of our lightest and most protective fabrics, for reliable defense against rocks, dirt, and debris. Ferrosi fabric wards off wind and rain and adds durability, stretch, and breathability for moving fast in rugged terrain. ActiveIce™ technology cools you as you sweat while providing UPF 50+ sun protection. The bottom of the gaiter is held securely by a dual attachment Hypalon strap, along with a hook/loop attachment for the back of the shoe or boot. Extra stick-on loops are included for trail runners. For long days on trail or when keeping debris out of footwear is a priority, the Ferrosi Hybrid Gaiters are built for logging miles in comfort.
