Inspired by classic military and rugged workwear, the FLEX-AST Cargo Pants are built for riders seeking a balance of style, comfort, and protection. These pants combine durable, stretch fabric with a sleek, utilitarian multi-pocket design for all-day comfort and flexibility. With integrated CE Level 1 Nucleon Flex Plus knee armour, the pants offer discreet, super-ventilated, and flexible impact protection, maintaining a refined, contemporary look.

Key Features
• Regular Tapered Cargo Fit: Regular fit with tapered legs and elasticated hems, available in both regular and short lengths. The short length is 5cm shorter compared to the regular version.
• Flexible Comfort: Lightweight, stretch fabric allows for maximum rider mobility without compromising on durability with mesh lining on the thighs and knees, plus soft-touch fabric on the inner pants and hip protector pockets, provide long-lasting comfort for extended rides.
• Military-Inspired Details: Herringbone tape accents on the pockets for easy access, metal D-ring, back loop, metal eyelets, and large belt loops emphasise the rugged cargo design.
• Ample Storage: Two secure cargo pockets with hidden snap buttons, two front and back pockets, plus a zip pocket on the right leg provide functional storage.
• Modern Finishes: Subtle tone-on-tone top-stitching, selvedge-look inner seams, and Alpinestars-branded buckle, snaps, and zipper pullers give the pants a refined, minimalist aesthetic.

Construction
• Built from a technical soft stretch performance fabric (polycotton twill blend with 3% elastane), the FLEX-AST Cargo Pants offer long-lasting wear and comfort.
• The soft-touch inner lining adds an extra layer of comfort, while functional cargo pockets offer practical storage for everyday essentials.
• The custom design features a regular fit with a Velcro waist adjuster and buckle closure to ensure a secure, personalised fit.
• Refined details like the tone-on-tone stitching and Alpinestars’ branded finishing hardware provide a polished, urban look.

Protection
