On the protection side, POC leverages their VPD (Visco-Elastic Polymer Dough) technology, an intelligent spongy material that goes from soft to hard during an impact. There are now three levels of VPD. The VPD 2.0 which you see in the middle graphic, now with the added VPD System at the top of the line and VPD Air which is the most lightweight offering. The whole protection range has been revamped around these new levels of VPD. On the DH protection side, you'll see VPD 2.0 - the bulkiest and least pedal friendly. On the enduro side, you'll find VPD System.
