MTB knee guard with Pro-Shape 2.0 protector, lightweight & extremely well-ventilated. The family of Dainese Trail Skins protectors represents the perfect balance between rideability & protection, allowing the rider to take on any discipline with maximum freedom of movement & in accordance with the highest international safety standards. The ideal choice for riders who plan to take on long uphill & downhill sections when out riding. The Trail Skins Air line focuses on lightness & breathability, optimizing the structure of protectors to maximize ventilation & contain overall weight. The Trail Skins Air knee guard is constructed around the Pro-Shape 2.0 protector, inspired by the geometry of auxetic materials present in nature that, following an impact or stress, expand in all directions simultaneously, increasing the area of coverage. The structure of the Pro-Shape 2.0 protector allows for maximum flexibility & adaptability whatever the knee position, tracing its movements throughout all phases of activity. It absorbs 83% of the force of an impact, rather than transmitting this to the knee. 55% of its surface area is completely open, ensuring ventilation & greater heat exchange during both the uphill & downhill phase. An ideal feature for riders who plan to take on long rides, even on the hottest of days. The knee guard remains stable, even during intense activity, thanks to a very long, transparent sock on the thigh & a practical elastic at calf height. The supplementary protector on the outside edges of the knee guard is designed to ensure protection even in case of sliding along the ground.
