Your level of safety shouldn't be determined by the size of your bank account. With this in mind, Troy Lee Designs is proud to introduce the SE4 Polyacrylite Helmet. A near carbon copy of its SE4 siblings, the lightweight SE4 Polyacrylite design incorporates the same triple-density EPS liner to better absorb low and high-speed impacts and reinforced chin bar with EPP liner. The SE4 Polyacrylite also utilizes the MIPS protection system, one of the most significant innovations in helmet technology in recent years. Add all these advanced features to the typical Troy Lee lever of fit, finish, and design makes the SE4 Polyarylite the best value in an off-road helmet today.
