The Alpinestars Flex-Ast 8 Motorcycle Denim Pants combine everyday styling with advanced riding protection and long-distance comfort. Crafted from A-TRAACX monolayer technical denim, the pants blend Cordura®, cotton, and nylon 6.6 yarns with integrated Cordura® and COOLMAX® technologies. The medium blue denim construction offers a durable, flexible option for riders who want motorcycle-specific performance without sacrificing a casual five-pocket appearance.
COOLMAX® moisture-wicking filament yarn helps pull sweat away from the skin to support breathable comfort during warm-weather rides and changing conditions. The multi-stretch fabric promotes freedom of movement, while the anatomically shaped design follows the natural riding position to help reduce fatigue during extended trips. Adaptive impact protection contours to the body for comfortable coverage and a secure fit while riding.
Durability is reinforced with hidden dual seams and overlock stitching on the external legs, plus double stitching and contrasting internal red overlock stitching. The abrasion-resistant fabric is engineered for lasting performance on and off the motorcycle. Practical finishing details include a metal zipper fly, selvedge-style edging to help prevent fraying, a leather back patch, branded belt loop and rivets, and an embroidered Astar pocket accent.
