The Anon Windham WaveCel Helmet combines the reliable durability of a hardshell helmet with the lightweight, space-age goodness of WaveCel construction. By incorporating 3D structured WaveCel into the protective EPS foam of the helmet, Anon is able to increase the helmet's effectiveness against direct and rotational impacts, all while reducing weight and aiding breathability. Last but not least, it's finished off with a magnetic buckle and a Polartec® grid fleece liner for a superior feel.
