The Anon Logan WaveCel helmet combines 3D cell protection with an in-mould construction of a lightweight shell lined with EPS and WaveCel. The model is kept slim and low in profile. WaveCel is a compressible cell structure that lines the inside of the helmet and can mitigate impact and rotational force by bending it, reduce impact velocity by compressing it, and redirect energy away from the head by displacing it. For added comfort and fit, a 360° BOA® adjustment system allows for quick and easy one-turn adjustments, and the Fidlock® magnetic helmet strap buckle can be easily operated with one hand, even with gloves on. Polartec® Power Grid® fleece lining and ear pads provide quick drying and warmth for comfort throughout the day. FeaturesWaveCel® works like a network of hundreds of interconnected shock absorbers that connect your head to the outer shell of the helmet. WaveCel® helps disperse impact energy through its network of cells, reducing impact forces similar to a car\'s crumple zone and then dissipating rotational forces by bending and shiftingThe in-mould exterior construction combines lightweight polycarbonate with EPS and WaveCel lining for elegance, comfort and a compact feelWeight: 424 gPassive ventilation channels underlay the WaveCel material with 10 ventilation channels that draw in fresh air at the front and wick away moisture at the backThe In-Shell 360° BOA® adjustment system with adjustment dials directly under the helmet shell for micro-adjustments around the entire headThe Fidlock® buckle with push-button closure uses magnets that allow the buckle to be opened and closed even with gloves and with one handExpedition Polartec® fleece on the lining and ear pads has a low pile, no fluff and wicks away moisture for maximum warmthCompatible with audio accessoriesCertificate: CE 1077B, ASTM 2040Anon guarantee: Anon products have a 1 year warranty from the date of purchase.
