The Alpinestars Racer Youth Graphite MX pants have been designed for all forms of off-road riding, made from highly durable poly-fabric with stretch rip-stop fabric with PU coating for stretch and a technical yarn for added durability. Stretch fabric panels in critical areas give movement and comfort. High-performance "Babel" knee flexion offers a unique open vent design for a slimmer fit compatible with Alpinestars knee braces. Pre-shaped, reinforced, and padded 3D knee construction is also equipped with a hidden stretch spandex expansion gusset for a personalised fit. The Racer Graphite pants are liner-less with overlock flat seams for superior comfort. A double overlap Velcro closure system at the waist with a high-strength ratchet system is adjustable yet highly secure. Durable poly-fabric reinforcement at the seat allows for added stability, and localised laser-cut perforated zones provide optimum air circulation. An ergonomic inner leg leather patch is longer for improved protection for the new Alpinestars protectors for optimised security.
