Alpinestars - Fluid Apex Pants

Alpinestars - Fluid Apex Pants

The Fluid Apex Pants are designed for riders who want moto pants that can handle crashes, roost, and long motos without feeling bulky.

Alpinestars keeps your legs free to move while the seat and inner knee shrug off heat and abrasion. Alpinestars blends pro-level mobility with abrasion zones that shrug off tip-overs.

Why We Like It

We like how the fit hugs the body without feeling restrictive, so you can stand, sit, and move around on the bike without fighting your gear.

Why It’ll Work for You

If you’re looking for pants that work with modern knee braces and guards, the cut and materials here keep everything sliding and moving like it should.
