Leading safety features, a durable hardshell design, and one-hand fit adjustability for distraction-free comfort. Anon's Windham WaveCel Helmet pairs everyday hardshell durability with the advanced impact protection of WaveCel technology. WaveCel is a collapsible cellular structure that lines the inside of the helmet. It's designed to flex, crumple, and glide to reduce rotational and direct impact forces. A 360° BOA Fit System offers a quick, micro-adjustable fit with the turn of a dial, and the Fidlock magnetic helmet strap buckle allows for easy one-hand operation, even with gloves. Polartec Power Grid fleece liner and ear pads maintain quick-drying warmth for all-day comfort. Sleek fixed vents keep the air flowing for fog-free goggles.
