The Manis V1 Goggle features a unique magnetic lens that nests in the pocket of the frame slightly to semi lock the lens in place. This provides extra security from losing your lens when you faceplant. The dual-pane lens has an anti-fog coating on the inside, triple layer foam with accent red face fleece, sublimated mountain topographic art with a embossed faux leather branded stitched on patch. Also included in a dual-pane transparent yellow lens for use on those low-light stormy days on the hill. The goggle kit is capped off with a microfiber carrying case and EVA goggle case. Works well with most helmets.
