The Anon Logan WaveCe®l helmet pairs 3D cellular protection with an in-mould 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 moves in three critical motions to help flex, crumple, and glide to help reduce rotational and direct impact forces. Additional comfort and fit features include a 360° BOA® Fit System with 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. WaveCel® WaveCel® behaves like a network of hundreds of interconnected shock absorbers connecting your head and the outer shell of the helmet. WaveCel® helps distribute the impact energy through its network of cells, reduces impact forces like the crumple zone of a car, and then helps divert rotational forces by flexing and gliding In-mould shell In-mould shell construction fuses a lightweight polycarbonate shell with an EPS and WaveCel liner for sleek comfort and a low-profile fit.
