The Ferrosi Thru Gaiters are the perfect lightweight gaiter for ounce-counting backpackers. The Ferrosi Thru Gaiter utilizes our best-selling Ferrosi fabric -- strong, stretchy, breathable, and comfortable -- to add to our legacy collection of protective gaiters. We use recycled, and bluesign® approved materials in a trail runner/low-profile hiking boots specific design in keeping with the ultralight ethos of modern thru-hikers. A shoelace hook and drawcord cinch at its top hem ensure a snug fit that keeps debris out of footwear, and a replaceable instep strap makes gear fixes on the go a breeze. A must-have for long days on the PCT, AT CDT, or other long-distance hikes, the Ferrosi Thru Gaiters truly are a thru-hikers best ally.
