We hybrid-mapped Ferrosi and ActiveIce™, two of our lightest and most protective fabrics, into a gaiter 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 your shoe. In addition, you'll receive extra stick-on loops for your trail runners.The Ferrosi Hybrid Gaiters are built for long days on trail or when you must prioritize keeping debris out of your footwear.
