Made of D-Skin cowhide leather , Dainese Super Speed Perf. motorcycle pants can be combined with the Super Speed 4 Perf. jacket and are designed for motorcycle riders who love sporty road riding. The solid leather construction with strategically placed perforations integrates S1 stretch fabric and stretch inserts , a combination that makes the Super Speed Perf. pants extremely comfortable and ergonomic without neglecting high standards of protection. Maximum safety is guaranteed by protective technologies derived from the apparel worn by MotoGP professional riders, such as the new sliders on the knees , which feature a lighter construction. In addition, owing to the Replaceable Slider System (RSS) , they are easily replaceable and adjustable to suit any individual riding style, without having to shift the Velcro fastening. Further, impact absorption is ensured by certified composite knee protectors and soft Pro-Shape 2.0 hip protectors . Featuring a zipper on the calf and Velcro at the hem, the Super Speed Perf. pants are designed to be worn with Dainese boots featuring “IN” construction, and easily attach to the jacket via a dedicated zipper. Localized perforation in the most strategic areas ensure extreme ventilation and maximum thermal comfort even when the temperature rises, making these pants extremely versatile and ideal to be worn even in warmer climates .
