Stanley Mouse

The Stanley Mouse x Grassroots California Collection celebrates the art, rebellion, and cultural impact of one of the most influential visual voices of the American counterculture. Known for shaping the look of psychedelic rock posters, outlaw biker imagery, and underground art, Stanley Mouse’s work is woven here into premium apparel and headwear built for everyday wear.

This collection blends iconic artwork, symbolic motifs, and classic patterns with Grassroots California’s signature construction and attention to detail. From embroidered hats and statement tees to layered outerwear, every piece balances bold design with wearable function, including elevated liners, hidden stash pockets, and thoughtful finishes throughout.

This collaboration honors a legacy while pushing it forward. Designed for collectors, riders, and anyone who carries the spirit of the road wherever they go.
