Detailed Description

Versatile Weather and Debris Protection for On or Off-Trail Use

The Ferrosi Trail Gaiters combine abrasion resistance, weather protection, and debris defense, perfect for long days in mixed alpine terrain.

Now redesigned, they feature our 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 strap 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.
