This layer essentially acts as a slip plane to mimic the brains own low-friction cerebrospinal fluid, which is the bodys natural defense against oblique impacts Patented visor release system ensures the visor is released with the correct pre-determined amount of force, effectively reducing the forces on the riders neck during an impact The inner and outer surfaces are engineered to minimize the effects of oblique impacts 6 EPS/EPP inner parts with 5 densities to effectively manage volume and impact perfromance Hydration tube channels are integrated into the helmets cheek pads for convenience and performance The fit can be tailored to the riders head thanks to the helmets crown and cheek pads, which are available as genuine spare parts in different thicknesses Alpinestars has introduced a in-house standard for the SM3 helmet to test the helmets chin to conditions heavier than the homologation standard, and in order to pass the Alpinestars standards, the shell thickness and the structure of the helmet design itself have both been optimized on the chin area for superior impact performance The inner and outer surfaces are engineered to minimize the effects of oblique impacts Equipped with an Emergency Release System and removable cheek pads to permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort Soft textile chin strap is 25mm for optimal safety and rider comfort Stainless steel D-rings ensure a tight and secure fit The SM3 medium size helmet weighs 1310g (ECE) and 1430g (DOT) The helmet is 06 homologated - Homologation indicates that a helmet can be used in races in EU countries (as of 2021 homologation: 06) Weight 2.22 kg (M) 2.23 kg (XL) Manufacturer number EAN 8059347572154 (XS) EAN 8059347572161 (S) EAN 8059347572178 (M) EAN 8059347572185 (L) EAN 8059347572192 (XL) EAN 8059347572208 (2XL) Fit & size chart chevron_right
