Designed for snowboarding and skiing — with the most advanced D3O tailbone padding. These also allow you to integrate with a shirt for back/spine protection by velcroing to the shorts. The Demon Flex Force XD3O X2 snowboard/ski impact shorts for women offers fantastic coccyx protection, and comfort. Perfect for snowboarders and skiers due to D3O's lightweight, flexible properties. D3O is a soft flexible material that will shape to your body comfortably. The big change happens when it takes an impact, all the polymers lock together protecting you against the impact. This means that the harder the impact, the greater the resistance to the force. D3O technology is a patented smart material known for its use in protective gear and impact-resistant products. The material is soft and flexible at rest, but upon impact, it instantly hardens due to non-Newtonian polymers within a dilatant fluid. This unique property allows D3O to provide effective impact protection without sacrificing comfort or flexibility. Widely applied in sports, industrial, electronics, and military contexts, D3O is utilized in helmets, knee pads, gloves, and other gear, offering a combination of comfort and enhanced impact resistance by dynamically adapting its stiffness in response to sudden forces.
