The Alpinestars Techstar Acumen MX pants offer a racing-inspired cut for advanced-level competition. Made from an advanced blend of stretch rip-stop fabric and 600D poly-fabric for enhanced stretchability and durability, with durable 4-way stretch on the yoke, thighs, and upper knees, the Techstar MX pants are ultra-durable and comfortable. They offer superior airflow thanks to the highly breathable Stretchnet zones with laser perforations for maximum comfort. The performance-engineered single-layer construction and liner-less design offer enhanced wearability, exceptional comfort, and lighter weight, providing an effortless on and off, even when worn with knee braces or knee guards. Goatskin leather inner knees offer a premium feel and durability with additional reinforcement at the seat and knees. A revised Babel knee gusset gives flexibility and ventilation; fade-resistant graphics keep vibrance after washing. The elasticated waist offers a silicon inner waist to keep these in position with a secure SX2 auto-lock magnetic buckle for secure closure.
