Skinny D3O® stands for maximum protection at low weight and allows for the greatest possible flexibility while riding. Equipped with D3O® technology, these protectors are the premium version of the classic Bluegrass Skinny models. D3O® material remains flexible under normal conditions. However, upon impact, it hardens in a fraction of a second and disperses the shock force outward. For a better fit, the protectors are slightly longer and feature silicone inner straps to ensure a perfect fit at all times. The material is reinforced with particularly durable Kevlar at particularly vulnerable areas.
