Hybrid-mapped ActiveIce(TM) and Ferrosi fabrics provide lightweight, breathable, and weather resistant protection with a dual attachment system for the most secure low-profile gaiter.Two of our lightest and most protective fabrics, hybrid-mapped into a gaiter for reliable defense against pesky rocks, dirt, and debris. ActiveIce(TM) technology actually cools you as you sweat, while providing UPF 50+ sun protection. Ferrosi fabric wards off wind and rain, and adds durability, stretch, and breathability for when you're moving fast in rugged terrain. The bottom of the gaiter is held securely by a dual attachment hypalon strap, along with a hook/loop attachment for the back of your shoe. You'll receive an extra pair of stick-on loops in the case that your trail runners don't come with that capability built in.SpecsPRODUCT :#279869FABRIC :bluesignA(R) approved 86% Nylon, 14% Spandex, 90D Stretch Woven Ripstop at back ankle, 92% Recycled Polyester, 8% Elastane Knit Jersey at center frontWEIGHT :1.8 oz/51 gFeaturesFABRIC PERFORMANCEWater ResistantWind ResistantMovement-Mirroring StretchBreathableLightweightAbrasion ResistantQuick DryingUPF 50+DESIGN FEATURESShoelace HookElastic Top HemReplaceable Hypalon Instep StrepLoop Attachment Point at Center BackBreathable Top PanelBalancing Shockcord for Close FitSold with Stick on Hook Tab to Attach to Your CurrentTrail Shoe
