EVO compression shorts offer the highest level of impact protection available. Strategic D3O® inserts and panels, breathable compression fabric, and designs that allow for freedom of movement make the Evo family stand out in the market. D3O® material hardens on impact but flexes during riding. Fit and technology, in addition to the redesigned EVO collection, have helped introduce the new PADLOCK connection system, which completely prevents protector migration before and during impact. With EVO and PADLOCK, you'll never have to compromise again. The PADLOCK connection system is our latest technology that connects internal protective elements, ensuring the protectors don't shift while riding or in the event of a crash. At the core of our system are the EVO jackets and shorts, which can be connected to a range of our elbow and knee protectors. Goodbye sliding protectors! Lock it and forget it. - Removable D3O hip protectors for CE 1621:1 protection - Comfortable Lycra construction with laminated EVA foam for thigh and tailbone protection and freedom of movement while pedaling - Silicone print to prevent the legs from riding up - PADLOCK connection system attaches to Evo jackets and DBO / Recon kneepads
