Alpinestars Fluid Kepler Pants 2027

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.

Features:
  • Sport-inspired fit: A relaxed on-bike profile helps reduce bunching and supports natural movement through standing, seated, and transitional riding.
  • Articulated shaping: Pre-curved leg geometry helps the pants sit correctly in the riding position for a more natural feel at the knees and hips.
  • Ride-ready comfort: A clean, low-distraction wear feel helps keep the pants composed and comfortable through long motos and repeated off-road sessions.

Protection:

  • Reinforcements are positioned on key areas including the back yoke, upper knees, and backs of the legs.
  • Reinforced 600D polyfabric on the seat and knees provides added durability in critical contact zones.
  • Synthetic leather on the inner knees delivers enhanced durability in a high-wear area.

Construction:

  • Ergonomic cut and 3D pattern construction.
  • Extended stretch corduroy fabric panels on the crotch, knees, back yoke, and inside legs.
  • 600D polyfabric main chassis with reinforced 600D polyfabric on the seat and knees.
  • Synthetic leather on the inner knees.
  • Mesh lining.
  • Ratchet closure.
  • Zippered fly.
