Best-selling Ferrosi fabric is so strong, stretchy, breathable, and comfortable, it made perfect sense to apply its renowned superpowers to our legacy of protective gaiters. The Ferrosi Thru Gaiters earned its name for its incredibly light weight that's perfect for ounce-counting backpackers, and fits trail runners and low profile hiking boots in keeping with the ultralight ethos of thru-hikers. A shoelace hook and drawcord cinch at its top hem ensures a snug fit that keeps debris out of your footwear, and a replaceable instep strap makes gear fixes on the go a breeze.
