Flexible elbow protector with innovative D3O protection. - modeled D3O insert inside, - Cordura construction provides flexibility - Stretch Kevlar protecting the front part of the protector with abrasion-resistant graphics, - ergonomic shape, - Velcro fastening strap at the top, - CE EN 1621-1 certificate Sixsixone has joined forces with d3o, market leaders in smart foam technology. The result of this collaboration is the EVO set, a new approach to the rigors of mountain biking for the 21st century. The inserts, utilizing revolutionary d3o technology, are made of a material whose intelligent molecules move with you as you move and, upon impact, clump together to absorb impact energy. d30 components utilize a unique flow system. Designed to provide both freedom of movement and exceptional protection, thanks to a macro-density mechanism that maximizes contact and minimizes the force transmitted during impact. Protectors utilizing this technology are also breathable for maximum comfort. Soft, lightweight, breathable, and flexible, the EVO inserts adapt to the absolute any driving style... Additionally, they offer excellent protection that goes beyond EU standards. - size: M - upper circumference (biceps): 26-31 cm
