The Leatt MTB 4.0 AllMtn V21 Bike Helmet leads the pack for Leatt's half-shell mountain bike helmet collection. This stalwart head protector uses two different densities of impact foam to defend against high and low speed crashes, 360 ̊ Turbine Technology to protect from rotational impacts, and 13 big vents to protect against your head turning into a hot sweaty mess. As an added bonus, the 4.0 includes a docking port for your shades and an adjustable visor that makes rooms for your goggles, so no matter your eye protection preference, it's got you covered.
