Alpinestars Youth Fluid Lone Jersey

Youth MX jersey in the Lone graphic

The Youth Fluid Lone Jersey is Alpinestars' entry-range motocross jersey for kids, in the Lone colourways, for young riders doing club days and trail rides rather than racing. It's a lightweight, breathable, moisture-wicking polyfabric with mechanical stretch built in, cut with a youth-specific ergonomic pattern and construction tailored to the graphic. The rear hem is extended to keep it tucked, and there's a sport collar at the neck.

Sizing and fit

Youth sizes YS to Y2XL in two colourways: Gray/Purple and Gray/White/Red. It's a relaxed athletic fit, so most kids take their normal size and still have room for a chest guard underneath.

Match it up

Made to match the Youth Fluid Lone Pants in the same colourways. Add Youth Radar Gloves and a Bionic Action Kids Chest Guard. Adults get the Lone graphic on the Racer Lone Jersey.
