Alpinestars Youth Fluid Amber Pants

Youth MX pants in the Amber graphic

The Youth Fluid Amber Pants are Alpinestars' entry-range motocross pants for kids, in the Amber colourway, made for track and trail riding where comfort and durability matter more than a race-tight cut. The build is lightweight 600D polyfabric with reinforced 600D at the seat and knees, synthetic leather on the inner knees for grip and wear against the bike, and extended stretch corduroy panels at the crotch, knees, back yoke and inside legs so they can move. Pre-curved legs with a 3D pattern, a mesh lining, ratchet closure and a zip fly.

Sizing

Youth sizes 22 to 30 (waist, inches), with the 30 added for bigger kids. It's cut for an attack stance but it's still a Fluid sport fit, so there's room for youth knee guards at their normal size, and the ratchet closure lets you take up the waist.

Match it up

Pairs with the Youth Fluid Amber Jersey. Add Youth Radar Gloves and SX-1 Youth Knee Guards. Adults get the Amber graphic on the Racer Amber Pants.
