The Fluid Kepler Jersey is a performance MX jersey for recreational motocross and off-road riding, combining a relaxed fit with race-derived styling from Alpinestars' premium gear lines. Constructed from lightweight, moisture-wicking polyfabric with breathable mechanical stretch, it is optimized for comfort, durability, and freedom of movement across demanding terrain. A longer rear cut and ergonomic fit enhance coverage on the bike while delivering an easy-wearing, coordinated Fluid look.
