Hammer is the new helmet conceived and designed specifically for off road, from MTB to enduro and up to e-bikes. Safety was the main inspiration for the design of both the front and the back, in order to protect the entire skull, thanks also to the In-Mold structure, which offers high mechanical strength and impact resistance. The compact design does not compromise ventilation, thanks to the dynamic study of the flows which has made it possible to identify the best structure to facilitate the passage of air even at lower speeds and at high temperatures, ensuring a pleasant sensation of freshness.
