Senseless - From Bicycle Magazine
"A lot of the innovation in helmets has been focused on making them lighter, more ventilated, and fit better," said John Thompson, bike helmet product manager for Scott Sports. "The customers leave it to the certifying authority to assure safety."
The certifying authority. That would be the Consumer Product Safety Commission. The federal agency sets out minimum standards to protect consumers against shoddy helmets.
But those testing standards aren't handed down by God on stone tablets. They come from somewhere.
- Spin Control - These systems incorporate an inner and outer shell, when a crash occurs the outer layer rotates away from the impact reducing probability of a concussion.
- Easing the Blow - Inner shell with many individual cells that compress against one another (think accordion) to reduce impact.

- Aerocore - Polymer form called Koroyd that replaces foam (30% reduction in force from EPS)
- Vinyl Nitrate - Soft Foam with a flexible shell (Good for high and low velocity impacts)
- MIPS - Multidirectional Impact Protection System - Addresses rotational forces with shells that move independently
- HIP-Tec - Multiple layers: rigid shell, EVA foam, and EPS
- Conehead - cone-shaped pockets of EPS foam that crush on impact that disperses energy laterally instead of vertically
