The Old School Cert was modified from the original 1973 Full-Tec and features a retro shape that sits low on your head, offering great impact protection. This season we added Mips or Multi-directional Impact Protection Systems for added protection against rotational impact. The full coverage terry and mesh liner along with the padded audio capable ear pads keeps you comfortable and warm on the hill. The 11 mesh covered vents add ventilation while keeping you safe from branches and debris.
