The Leatt MTB Gravity 4.0 in Stealth Black/Grey is an award-winning full face mountain bike helmet that delivers ASTM downhill-certified protection and outstanding ventilation at a fair price. It’s a great option for everything from enduro to bike park laps and e-bike trail cycling.

If you want a dedicated full face helmet that won’t overheat you on warm days, this is the one we’d suggest. It suits cyclists moving into bike park and downhill cycling, as well as enduro cyclists who want full-time chin protection without a heavy, stuffy helmet.

22 Vents and Removable Mouthpiece Cover

With 22 vents and a clever modular mouthpiece that can be removed to boost airflow, the Gravity 4.0 is one of the best ventilated full face helmets around.

360° Turbine Technology

Leatt’s 360° Turbine Technology uses small, energy-absorbing discs inside the helmet that can move in any direction on impact. They help reduce head impact at concussion level by up to 30% and rotational acceleration to the head and brain by up to 40%, giving you extra confidence every time you head out.

DH-Certified Lightweight Shell

The lightweight polymer shell is ASTM downhill certified, with in-moulded EPS and EPO impact foam for superior energy absorption. The visor has a breakaway function to help reduce rotational forces in a crash.

Comfort and Convenience

The Dri-Lex liner is moisture-wicking, breathable, anti-odour and washable. Optimal neck brace compatibility and the easy-to-use Fidlock magnetic buckle make it practical for long days at the bike park.
