The Stella ST-1 Waterproof Jacket is designed for riders who want dependable weather protection and comfort for road touring in changing conditions. Built around a women’s-specific touring fit, the jacket uses a fixed waterproof membrane to provide reliable wet-weather performance while maintaining breathability during longer rides. Front chest vents increase airflow to help manage temperature on the move, while pre-curved arms and ergonomic elbows support natural mobility in a riding position. A modern shoulder design with Alpinestars branding gives the jacket an adventure touring–inspired appearance suited for everyday use and travel.

A detachable thermal liner with 80g insulation in the torso and sleeves is secured with snap button connections and can be removed as conditions warm. When not in use, the liner stores in the lower back cargo pocket for convenience. Storage includes expandable front cargo pockets, a zippered chest pocket, inner mesh pockets including one waterproof pocket, and a rear cargo pocket for carrying essential items. Fit can be adjusted at the biceps, collar, cuffs, and waist, and an extended rear cut improves coverage while riding. Tech-Air® Ready construction, CE Level 1 Nucleon Flex Plus shoulder and elbow armor, and full CE certification provide dependable impact protection, while a pant connection zipper helps prevent wind ingress when paired with the Stella ST-1 Waterproof Pants.
