ALPINESTARS ST-1 WP Jacket

All-weather waterproof motorcycle jacket designed for ergonomic mobility, comfort, and dependable protection during adventure touring and street riding. The detachable waterproof thermal liner helps keep the rider warm and comfortable, while front chest vent panels provide cooling airflow and improved breathability in changing conditions.

Pre-curved arms and ergonomic elbows promote excellent freedom of movement, while the modern shoulder design delivers an adventure touring-inspired look. The detachable liner features 80g torso and 80g sleeve insulation with snap-button connections to anchor it securely to the jacket. When not in use, the liner can be stored in the lower back cargo pocket.

Tech-Air® ready, the jacket includes Nucleon Flex Plus elbow and shoulder armor for effective impact protection. A fixed membrane liner enhances rider comfort and includes internal pockets for a divided chest protector and a back protector pocket; both protectors are available as optional extra accessories.

Storage options include 2 front cargo pockets, 1 lower back cargo pocket, 1 zippered chest pocket, and 2 inner mesh pockets for versatile, secure storage of valuables. Sleeve volume adjusters with press buttons on the biceps, plus hook-and-loop collar, cuff, and waist adjusters, provide a tailored fit. An extended back cut offers greater coverage while riding, and the pant connection zipper helps ensure a secure fit while preventing wind ingress.
