POC's Spine VPD 2.0 Vest gives you full spinal protection with great flexibility and freedom of movement. It uses Visco-Elastic Polymer Dough that forms to your body and is flexible when moving, then turns rigid upon impact. It's so tough, the 3D molded VPD 2.0 complies to motorcycle standards. The vest is highly breathable, and the pad is removable for washing. Obviously, fit is incredibly important for something like this, so the Spine VPD has height adjustable and removable waistband with two width options, for the perfect fit.
