The LEATT MTB Gravity 4.0 helmet offers DH-certified protection in a breathable, lightweight design, ideal for enduro riders, bike park days and electric MTB outings. Molded dual-density EPS + EPO foam, combined with Leatt's Turbine 360° technology, protects against low- and high-speed impacts, as well as rotational forces, forming a 3-in-1 safety system you can rely on when the trail gets technical. A removable chin strap cover lets you customize airflow, while 22 vents ensure optimal air circulation even at low speeds. The Dri-Lex® lining is moisture-wicking, breathable and washable for optimum comfort over long distances, while the Fidlock magnetic buckle makes donning and doffing quick and easy. DH-certified, neck-protector compatible and well-priced, the Gravity 4.0 offers reliable protection for time trial racing.DETAILS:Approvals: AS/NZS 2063:2008, ASTM F1952-10, EN1078, CPSC 1203Protection info: Combined with impact foam, Turbine 360° technology offers a unique 3-in-1 safety system, protecting against low- and high-speed impacts, as well as rotational forces.Shell material: Polymer compositeFoams: Breathable, odor-resistant and washable Dri-Lex® inner liningProtective foams: EPS and EPO molded impact foam for superior energy absorption.Closure system: Fidlock magnetic buckleProtection system: 360° TurbineVentilation system: Maximum ventilation with 22 vents; removable chin strap ventilation coverVisor: Detachable visor - fall protection to reduce rotational impact forceWEIGHT: From 850 g (1.87 lb)SIZES:S: 55-56 cm.M: 57-58 cm.L: 59-60 cm.XL: 61-62 cm.
