The Ski Helmet Anon Logan WaveCel offers advanced protection with premium fit and comfort features in a lightweight, unobtrusive style. The WaveCel technology behaves like a network of hundreds of interconnected shock absorbers linking your head and the helmet's outer shell. It helps distribute shock energy in the event of a fall through its network of cells. Like a car's crumple zone, it reduces impact and helps divert rotational forces by flexing and sliding. Molded shell construction fuses a lightweight polycarbonate shell with an EPS liner for sleek comfort and a low-profile fit. Passive ventilation channels contribute to breathability, with individual vents drawing in cool air at the front and wicking away moisture at the back. This description is an automatic translation.
