ALPINESTARS ST-1 Waterproof Pants

These waterproof pants are built for riders who want dependable all-weather coverage with a clean, functional design. Constructed from 600D poly fabric with poly ripstop reinforcement on the inner legs, they balance flexibility and protection while maintaining a streamlined, comfortable fit for long days in the saddle. A fixed waterproof liner helps block wind and rain, making them a reliable choice when conditions turn unpredictable.

Designed with an ergonomic active fit, pre-curved legs, and 3D-shaped knees, they allow natural movement and comfort in the riding position. A detachable 80g thermal liner adds warmth for colder starts and evening rides, while multiple cargo and internal pockets provide practical storage for essentials. Finished with fit adjusters at the waist and cuffs, an extended rear cut for added coverage, and a pant connection zipper, they offer versatile performance for adventure touring and everyday riding throughout the year.
