Alpinestars Youth Fluid Lone Pants

Youth MX pants in the Lone graphic

The Youth Fluid Lone Pants are Alpinestars' entry-range motocross pants for kids, in the Lone colourways. Fluid is the relaxed-fit end of the Alpinestars MX line-up, and the build is the proven one: lightweight 600D polyfabric with reinforced zones at the seat and knees, synthetic leather on the inner knees for abrasion against the bike, and extended stretch corduroy panels at the crotch, knees, back yoke and inside legs. Pre-curved legs with a 3D pattern, a mesh lining, ratchet closure and a zip fly.

Sizing

Youth sizes 22 to 30 (waist, inches) in two colourways: Gray/Purple and Gray/White/Red. It's a sport fit with a streamlined silhouette rather than a race cut, so most kids take their normal size with youth knee guards underneath, and the ratchet closure snugs the waist as they grow.

Match it up

Made to match the Youth Fluid Lone Jersey in the same colourways. Add Youth Radar Gloves and SX-1 Youth Knee Guards. Adults get the Lone graphic on the Racer Lone Pants.
