Trusted Ferrosi fabric redesigned into a gaiter to keep debris out of shoes for durable, stretchy, weather resistant footwear protection. Weighing 60g! OR's 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 gram-counting backpackers, and fits trail runners and low profile hiking boots in keeping with the ultralight ethos of thru-hikers. The Ferrosi Thru Gaiters are designed for secure and reliable protection. Crafted with a shoelace hook and drawcord cinch at its top hem for a superior fit, it keeps debris and elements out of your footwear. The replaceable instep strap also makes gear fixes and adjustments easy on the move.
