Thanks to the in-moulded EPS design, the Speedframe MTB Helmet gives you exceptional crash protection as well as long-term durability. In the event of a crash, the EPS foam provides impact absorption, while the outer shell will fend off the inevitable scuffs, scratches and knocks of mountain biking. You'll also benefit from the brain-protecting Multi-directional Impact Protection System (MIPS). MIPS (Multi-directional Impact Protection System) The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head. Rotational motion is a common cause of concussions in oblique hits to the head. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head. Talking fresh, the moisture-wicking liner stops the sting of sweat in the eyes and it's removable to make washing easy. The 360°Fit System lets you dial in the fit, literally - the rear dial offers quick and easy control of the fit so comfort is easy to get and the Speedframe remains in place in the event of a crash. Lastly, the visor is adjustable and goggle compatible, giving you the best eyewear versatility to suit your riding style.
