Key Features: Main knee sleeve fabric with four-way stretch that is highly breathable and feels like second skin for all day pedalling comfort. Ergonomic patterning behind the knee and wide leg gripper higher up on the thigh stop slippage and keep pads in place. Knee pad inserts designed specifically for Rapha in collaboration with RHEON™ Labs to control and dissipate high levels of impact. Pads are made with an active polymer that is soft and flexible for freedom of movement but intelligently strengthens when subjected to force. Front fabric constructed from SuperFabric™, a tough synthetic with a proprietary ceramic polymer print that is incredibly durable. Rapha Trail Knee Pads feature Level 2, Type B protection – the highest certified level of protection found in a pair of lightweight knee pads. How to wear: Designed to work in tandem with the Men’s / Women’s Trail Shorts or Men’s / Women’s Trail Pants. Position the upper leg gripper against the skin above or underneath Men’s Trail Cargo Bib Liner Shorts or Women’s Trail Liner Shorts to prevent slippage.
