Limited Edition • Artist Collaborations • Hidden Stash Pockets • It's A Movement •
For more than 17 years, Grassroots California has made headwear for artists, festival grounds, venues, brands & everything in between. Hats you spot in the crowd at a show, on the lot before doors and at the campsite long after the last set.
Every drop is a small run. Some are designed in-house by our team, others with the independent artists, musicians and festivals we grew up on, from Jimbo Phillips and Android Jones to Stanley Mouse and Killer Acid. Every piece is Limited Edition, and when a design sells through, we're on to the next one.
Look closer and you'll find what sets each piece apart: dense embroidery, bold sublimated prints, satin liners and a hidden stash pocket inside every structured hat. The details are there for the people who look for them.
Stop by our Denver flagship Monday through Saturday, and know that a percentage of every purchase goes back to the artists and communities behind the designs. If you know, you know.
