Constructed from single-layer A-TRAACX technical denim with integrated COOLMAX® technology, CORDURA®, cotton, and Nylon 6.6, the pants deliver excellent abrasion resistance and long-lasting performance.

Ultra-slim and adaptive, the protectors provide extensive coverage and effective impact protection without compromising comfort or freedom of movement—ideal for riders seeking refined, AA-rated technical riding denim with a classic casual look.
