Comfortable, Flexible Elbow Protection with revolutionary. D3O is a soft material that gets very hard very fast on impact. It gives you the best of both worlds for cycling protection.
D3O is a protective material that is specially designed to be lightweight and withstand high impacts. The construction of the d3o material is flexible and pliable when left alone but at the point of force in the area of an impact the material stiffens to form a hard shell, thus distributing the force of the impact throughout the rest of the material. After the impact force reverberates through the d3o material it again returns to its original flexible form. Since the d3o material is so light and durable it is ideal for body armor and pads, forming to the movements you make when you ride or skate, d3o is an ideal material for any piece of protective gear.
