Always a favourite with cyclists who demand both comfort and performance, the Synthe design gets some tweaks to make it better than ever. The Synthe II Helmet (MIPS), is equipped with the MIPS (Multi-directional Impact Protection System) brain protection system. This works alongside the In-Mould polycarbonate shell and Thermoformed SL Roll Cage to deliver superb levels of impact absorption and head protection in the event of a crash. 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. You'll also be pleased to find the Synthe II is fast and fresh. The compact design slips through the air with minimal drag, ensuring very little wasted watts as you pick up speed. And not just that, a total of 19 Wind Tunnel vents and carefully designed internal channels create a rush of air over the head, keeping you feeling great as you warm up. X-Static anti-microbial padding is also there to keep you feeling comfortable. Quick to wick away sweat before discomfort sets in, it's also great at preventing bacterial build-up that can cause an itchy head. Cool, dry and fresh. Perfect. Roc Loc 5 Air MIPS Inside the Synthe II is the light and airy Roc-Loc 5 Air fit system. This is the industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing fit and comfort, Roc Loc 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand. And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.
