Alpinestars Fluid Kepler Pant

The Fluid Kepler Pants are MX pants designed for motocross riders seeking all-day comfort, mobility, and a more relaxed performance fit on track and trail. Built on a lightweight yet durable 600D polyfabric chassis with stretch panels, ergonomic patterning, and a pre-curved leg design, they deliver natural movement and dependable toughness in the riding position.
