Alpinestars Flex-Ast Cargo

The Alpinestars Flex-Ast Cargo Motorcycle trousers combine military-inspired style with modern rider protection. Built from a durable stretch polycotton twill blend, they deliver comfort, flexibility, and everyday practicality both on and off the bike.

Designed for long-lasting wear, the trousers feature a mesh lining on thighs and knees plus soft-touch inner fabric for extra comfort. The regular tapered cargo fit with elasticated hems ensures a modern look, while options in regular and short leg lengths guarantee the right fit. A Velcro waist adjuster with buckle closure provides a secure, personalised feel.

For safety, the Flex-Ast comes with CE Level 1 Nucleon Flex Plus knee protectors, lightweight, ventilated, and adjustable via three internal positions. The trousers are fully CE-certified to EN17092-4:2020 (Class A), offering reliable impact protection for urban and casual riding.

Practicality is central to the design. Cargo pockets with hidden snaps, standard front and back pockets, and a discreet zip pocket provide ample storage. Rugged details such as herringbone tape, metal D-ring, branded hardware, and selvedge-look seams reinforce the cargo-inspired look while keeping the finish refined.
