During the past years the number of cycling helmets with MIPS protection has increased. It naturally adds to the price, but there is also quite a benefit.
The MIPS protection layer inside the helmets in part prevents your head to twist when your helmets hits the ground in case of a crash. Your helmet may twist or roll due to friction between your helmet and the ground.
According to the inventor, a Swedish neurosurgeon, there is still a greater potential in improving cycling helmets as he explains in the article.
