The lazer helium is a nice helmet.
In a well-designed and manufactured helmet mips can mimic a layer of cerebral fluid and allow for a small level of low-friction movement. It and some other newer technologies (conehead etc.) bring some small improvements to protection….that’s good. People shouldn’t be thinking though that in a hard impact today’s bicycle helmets will prevent the concussion effect of blood vessels stretching or tearing against the skull or the damaging of cranial nerves….simply because of how the brain will move with impact. There could be a helmet that does offer stronger protection but it would be too heavy, hot and not stylish enough for the average person....perhaps future technologies will get us closer. There are a number of ways a helmet can help with head injuries though and that makes it important enough to wear one. I’ll repeat the idea of learning how to instinctively fall in ways that protects against head impact is important to help with concussions especially at the slower speeds of most bicyclists.
