After the wild success of aramid bridge technology in its mountain bike helmets, POC integrated the same technology into the winter Fornix Helmet. Aramid bridge construction offers massive energy dispersion during impact while keeping the helmet shell lightweight and comfortable on your head. As a crowning touch, the Fornix helmet includes an adjustable venting system that pulls hot air and moisture away from your head with lightning speed and ultimate efficiency.
