These trousers are the perfect complement to the ST-1 WP Jacket, offering riders a fully waterproof construction combined with Alpinestars' renowned ergonomic mobility. Constructed from a durable 600D poly fabric blend with ripstop fabric reinforcements on the inner legs, these trousers offer excellent durability and connection with your motorcycle.

The Alpinestars ST-1 waterproof black trousers are designed with an ACTIVE touring fit, featuring pre-curved legs, 3D ergonomic knees, and a comfortable crotch construction to ensure superior freedom of movement and exceptional riding comfort on long journeys. A fixed waterproof liner guarantees all-weather performance, keeping you dry in even the heaviest rain. For added versatility, these trousers come with a detachable 80g thermal liner, providing warmth during cold mornings and evening rides, making them suitable for year-round use. A fixed mesh liner further enhances rider comfort by improving airflow against the skin. Practicality is also key, with two front zippered pockets offering secure storage for valuables and personal items. The lower leg hook and loop ankle adjusters, along with waist volume adjusters, allow for a tailored and secure fit. For added safety, reflective detailing on the thighs enhances visibility during low-light conditions. Additionally, a pant connection zipper allows for secure attachment to any Alpinestars motorcycle jacket, preventing wind ingress and ensuring a cohesive riding suit.
