Alpinestars Fluid Apex Pants

Entry-level MX pants with the most relaxed fit

The Fluid Apex Pants are the entry point to Alpinestars' motocross gear, made for recreational riders and anyone who doesn't want a race-tight cut. Fluid borrows the construction from the Supertech, Techstar and Racer lines and gives it the most relaxed fit of the four: a lightweight 600D polyfabric chassis with reinforced 600D on the seat and knees, stretch corduroy panels at the crotch, knees, back yoke and inside legs so you can move, and synthetic leather on the inner knees for grip and wear against the bike. Pre-curved legs, a mesh lining and a ratchet waist closure round it off.

Sizing and fit

Waist sizes 28 to 38 in three colourways: Blue/Yellow Fluoro, Multicolour and Yellow/Black. Sport fit, so there's room for knee guards underneath without sizing up, and the ratchet closure lets you fine-tune the waist. Women's cut: the Stella Fluid Apex Pants.

Match it up

Made to match the Fluid Apex Jersey. Add Radar Gloves and SX-1 v2 Knee Guards, and for kids there's the Youth Fluid Apex v2 Pants.

The Fluid line offers recreational MX riders gear with optimal MX technology that leverages the key construction features of the Supertech, Techstar, and Racer lines for a total performance look and feel that is optimized for comfort and riding functionality. Developed and tested on some of the toughest terrains around the globe, the sport fit Fluid gear is ideal for many forms of off-road riding and provides the most relaxed fit of all the MX26 gear lines.
