Alpinestars Flex-AST Cargo Motorcycle Textile Pants

The FLEX-AST Cargo Pants from Alpinestars combine urban style with functional motorcycle clothing. Designed for riders who value comfort, freedom of movement, and a robust design, these pants offer a regular fit with tapered legs and elastic hems. Available in regular and short lengths—the short version is 5 cm shorter and ideal for smaller riders.

Features:

The lightweight stretch fabric, made from a polyester-cotton twill blend with 3% elastane, ensures maximum freedom of movement without compromising durability.
Mesh lining on the thighs and knees, as well as soft material on the inner pants and hip protector pockets, provide long-lasting comfort – even on longer rides.
Military-inspired details such as herringbone tape on the pockets, metal D-ring, rear loop, metal eyelets, and large belt loops emphasize the functional cargo design.
Two secure cargo pockets with hidden snap buttons, two front and back pockets, and a zippered pocket on the right leg provide practical storage space.
Subtle tone-on-tone decorative stitching, selvedge-look inner seams, and buckles, snap fasteners, and zipper pulls with the Alpinestars logo create a sophisticated, minimalist look.
The regular fit with Velcro fastener at the waist and buckle closure allows for a secure, individual fit.

How to measure your height:

1 Waist

Measure your waist at the narrowest part of your torso, usually just above your belly button. Stand upright and keep breathing normally while you place the tape measure horizontally around your body. Make sure the tape is not digging in but also not too loose, so you get a realistic measurement.

2 Hips

Measure your hips at the widest part of your buttocks. Stand upright with your feet about hip-width apart and place the tape measure horizontally around your body. Make sure the tape stays at the same height all the way around and does not slip up or down.

3 Inseam

Measure your inseam from the crotch down along the inside of your leg to the sole of your foot. Stand upright, ideally without shoes and with your legs slightly apart. Run the tape measure straight down and make sure it does not slip.

4 Thigh

Measure your thigh at the fullest part. Wrap the tape loosely around your leg without pulling it tight. For an accurate result, stand relaxed and distribute your weight evenly on both legs.
