Scotty Cameron Supercharger Script T-ShirtScotty Cameron Supercharger Script T Shirt Reminiscent of the butterfly valves on the supercharged dragsters Scotty and his dad would watch back in the day, Scotty's putters have been identified by three bright red dots for years. Crafted from an ultra soft, comfy 60 40 cotton poly blend with a Circle T at the hip and a new Speed Shop design on both sides, this new t shirt in dark heather gray celebrates the spirit of the supercharger.
