Extensive coverage and superior ventilation thanks to POC Coron Air MIPS. This helmet has been in our equipment closet for a long time. , and we prefer it to most full face helmets when we rush down the mountain and put everything on the line. You see while most helmets cover the entire face have a polystyrene foam lining designed to withstand only one blow POC Coron has a durable fiberglass shell and polystyrene foam lining able to withstand repeated impacts. This gives us an extra layer of protection so we can confidently continue to charge throughout the riding season. The latest model of POC abandons SPIN technology in favor of a MIPS liner to protect against impact forces during lower speed rotations.
