Alpinestars Flex-AST Cargo, textile pants

Inspired by classic military and rugged workwear, the Flex-Ast Cargo Pants are designed for urban riders seeking a balance between style, comfort, and protection. These pants combine durable, stretchy fabric with a sleek, utilitarian multi-pocket design for all-day comfort and flexibility.

With integrated Level 1 Nucleon Flex Plus knee protectors, the pants offer discreet, super-ventilated, and flexible impact protection while maintaining a refined, contemporary look.

Features

• Regular tapered cargo fit: Regular fit with tapered legs and elastic hems, available in regular and short lengths. The short length is 5 cm shorter than the regular version. Flexible comfort: Lightweight stretch fabric allows maximum rider mobility without compromising durability, with mesh lining on the thighs and knees and soft fabric on the inside of the pants and hip protection pockets, providing long-lasting comfort for longer rides.
• Military-inspired details: Herringbone tape accents on the pockets for easy access, metal D-ring, back loop, metal eyelets, and large belt loops emphasize the rugged cargo design.
• Ample storage: Two secure cargo pockets with hidden snaps, two front and back pockets, and a zippered pocket on the right leg provide functional storage.
• Modern finishes: Subtle tone-on-tone topstitching, selvedge-like inner seams, and Alpinestars-branded buckle, snaps, and zipper pull give the pants a refined, minimalist aesthetic
