Our Geo Hat represents Sendero's geological foundations, and pays homage to the natural world beneath our feet. This special edition Geo Hat has a 1970's map of the Paria NW Quadrangle printed on the inside of the hat. Now this isn't just a random map, but it's where El Jefe spent his summers working on his dissertation.
