The Skull Dura Comp SPIN helmet introduces a new, innovative Race Lock system that allows riders to perfectly fit the helmet to their head, eliminating helmet vibrations at high speeds. The size adjustment dial is flush with the helmet shell, eliminating neck pressure. The new liner shape ensures a consistent fit. The new Fidlock buckle guarantees a secure fit and is easy to operate with gloves. The helmet is FIS RH 2013 certified. The aramid-reinforced VPD front panel provides additional protection against repeated impacts. The helmet core is made of multi-layer EPP, while the shell is made of highly durable ABS/PC. The helmet also features our patented SPIN technology. Removable ear pads make it easy for medics to safely remove the helmet in an emergency.
