The Outdoor Research Ferrosi Trail Gaiter features a redesigned legendary Ferrosi fabric: a bluesign-approved recycled nylon blend that's lightweight, durable, and water-resistant. A low-profile elastic cinch at the top hem, boot lace hook, and durable Hypalon instep straps deliver a secure, snug fit on long hikes and approaches. The adjustable internal instep strap lets you fine-tune the fit, and an offset hook-and-loop closure makes it easy to distinguish left from right. Reflective logos enhance visibility in low-light conditions. An essential accessory for traveling on technical trails or cross-country mountain adventures, the Ferrosi Gaiter delivers versatile, durable protection for all-day alpine wear.
