The FLEX-AST Cargo motorcycle trousers from Alpinestars combine a military-inspired cargo style with technical motorcycle gear. These motorcycle trousers are made from a soft stretch polycotton twill (97% cotton/polyester blend with 3% elastane), offering both long-term durability and plenty of freedom of movement.
The regular-fit FLEX-AST Cargo motorcycle trousers feature tapered legs with elasticated cuffs. In practice, this means sliding your motorcycle boots inside the motorcycle trousers will be a challenge. You can choose between a regular length and a short version that is five centimetres shorter. A Velcro waist adjuster and buckle closure provide a personalised fit. Large belt loops, a metal D-ring, metal eyelets and herringbone tape accents on the pockets underline the rugged cargo design.
The light stretch fabric of the FLEX-AST Cargo motorcycle trousers allows maximum mobility without compromising wear-resistance and longevity. Mesh lining at the thighs and knees improves breathability. The soft inner lining and soft fabric in the hip protector pockets ensure long-lasting comfort on longer rides. The hip protectors themselves are available as an option.
Two cargo pockets with hidden press studs, two front and two back pockets, plus a zipped pocket on the right leg provide practical storage. Tone-on-tone stitching, selvedge-look inner seams and Alpinestars-branded buckle, snaps and zip pullers give these motorcycle trousers a clean, minimalist look.
Nucleon Flex Plus knee protectors are flexible, ventilated and low profile. These Level 1 protectors are height-adjustable for a more personalised fit.
These motorcycle trousers meet EN 17092-4:2020 – Class A and are CE Category II certified.
