Description
Race-ready aero performance with a precise BOA® FS2 fit system. The Endurance 5.0 Helmet is designed for XC and gravel racers who demand advanced protection, maximum ventilation, and long-lasting comfort. Its lightweight polymer shell with an aero shape reduces drag, while 360° Turbine EVO Tech and optimized EPS impact foam form a 3-in-1 safety system that protects against low-speed impacts, high-speed impacts, and rotational forces. The BOA® FS2 Fit System provides precise, adjustable comfort, and a magnetic Fidlock buckle allows one-handed closure. Weighing just 280g (size M) with an eyewear docking port and washable inner liner, the Endurance 5.0 is ready for race day or epic rides.

Size guide
Leatt helmets
Fit tip If you land between two sizes, go up a size and dial the helmet in with its fit adjuster.
How to measure
Take a soft tape measure and wrap it around your head about 2 cm above your eyebrows and the tops of your ears, keeping it level all the way round. Note the measurement in cm and find it in the table. If you land between two sizes, go up a size and dial the helmet in with its fit adjuster. A helmet should sit level, snug but not tight, and not move when you shake your head.
