The Old School Certified helmet was modified from the original 1973 Full-Tec and features and retro shape that sits low on your head offering great impact protection. The premium heat-sealed liner keeps you comfortable and the 11 open vents keep you cool. The rounder shape holds to anyones head.
The Old School Classic Certified is equipped with EPS foam and is multi-certified for CPSC CE ASTM and AS/NZS 2063:2008. The protective industry jargon in that last sentence means a massive machine smashed this helmet against an anvil in a scientific setting to prove to the world it will keep your precious dome safe when you slam.
