This is for the skier who is fully aware of the dangers and hazards of their sport. POC’s Spine VPD tee is a short sleeve jacket with shoulder-cups, breast plates and a back protector. This tee provides tons of protection, but also allows for lots of mobility to make sure you do not have to test out its protection capabilities. The VPD is a revolutionary material that is soft until impact and then it stiffens to provide protection.
