APPROVED BY D3O®D3O® is a world-renowned specialist impact protection company, that uses its unique knowledge and know-how to advise regulatory bodies on the best practice for impact protection. D3O® is a patented material proven to deliver superior impact protection through advanced shock absorption. D3O® is used by the military and medical field as well as in workwear, sports apparel, motorcycle apparel and footwear. D3O® material has a unique molecular structure that is soft and flexible, but on shock, the molecules lock together causing impact energy to dissipate which reduces force and then returns to its flexible state. The greater the force of the impact, the more the molecules lock together and the greater the protection.
