A lightweight technical sport pant engineered to offer protection and superior riding comfort on sport and naked bikes, the SP-Pro’s pattern draws on Alpinestars expertise in racing garments to create an ergonomic, pre-curved shape that combines a sporty cut with comfort details to deliver the best riding experience. This pant is constructed using a new 14oz HDF stretch CORDURA® denim outer shell for superior resistance to abrasion, while still remaining flexible, with aramid knitted lining in the most exposed areas for extra abrasion resistance and effective heat transfer reduction. It is also equipped with RIDEKNIT® inserts on the back yoke, knee and calf for optimized freedom of movement and comfort, and a connection zipper to fit to any Alpinestars jacket.
