"Head down the trail with classic style and advanced design with the ATV Tek Bandana Dust Mask. This old-school bandana-style ATV dust mask has a sewn-in filter that blocks 99.5% of all dust particulates. This ensures dust-free air inhalation and a more enjoyable riding experience. Two 1-way exhaust valves reduce lens fogging and release heat, CO2, and water vapor. Suspension straps and the integrated 3D nose box gives a custom, comfortable fit. It's made from a breathable, moisture-wicking material that keeps you cool and comfortable. When the mask gets dirty, simply remove the tek valves, wash it, let it air-dry, and you've got the best dust mask for universal fit and comfort for riders of all ages. Accommodates neck sizes up to 20"". Helmet- and goggles-compatible.
