Visco Elastic Polymer Dough (VPD) 2.0 – VDP 2.0 offers better flexibility in cold temperatures and has increased tear resistance. To further improve anti-penetration properties, the back protector has an integrated, durable thermoplastic polymer sheet for extra protection at the spinal area. The slightly revised material compound is still highly dampening, soft, comfortable and adapts to create an individual fit. When exposed to impact, the material stiffens and has an extreme absorption of energy.
