Santa brought me a new Lazer G1 mips to replace the one that saved my head in a crash recently. The trauma doctors could not believe that I did not have a concussion given the extent of other damages to my body. The helmet was cracked and dented at the occipital bone area, so, one might surmise MIPS might have decreased the rate of deceleration. N = 1. Sold here. Besides, the ventilation and comfort on that helmet is fantastic.
