The Hip VPD 2.0 Shorts offer great freedom of movement and provide a high level of protection for your tailbone and hips. VPD adapts to the shape of your body, but when exposed to impact, the material stiffens and has extreme impact absorption properties. The Hip VPD 2.0 Shorts are flexible due to the stretch and ventilated mesh construction. The perforated 3-ply VPD 2.0 hip protection complies to the 1621-1 motorcycle standard.
