Anon's Logan WaveCel helmet pairs 3D cellular protection with an in-mold construction featuring a lightweight shell with an EPS and WaveCel liner designed in a sleek, low-profile style. 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. Additional comfort and fit features include a 360 deg BOA (R) Fit System with 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.
