Anon's Merak WaveCel helmet pairs revolutionary WaveCel protection with the dual hybrid construction of the ding-resistant durability of an endure-shell on top and a featherweight in-mold construction on the bottom with 19 active ventilation channels. WaveCel is a collapsible cellular structure that lines the inside of the helmet and can reduce impact and rotational force by flexing to reduce initial force, crumpling to lower impact velocity, and gliding to help redirect energy away from the head. A 360 deg BOA (R) Fit System offers a quick, micro-adjustable fit with the turn of a dial, and the Fidlock (R) magnetic helmet strap buckle allows for easy one-hand operation, even with gloves.
