Inspired by the Golden Ratio, the Phi is a beadless putter that is slightly less stable than the Penrose. It features a semi-deep profile with a smooth, rounded geometry that is stable enough to handle headwinds and tackle long approach shots with unmatched glide. Those looking to test out a beadless option for putting or a versatile and dependable driving putter, look no further - the Phi is the new golden standard of putt and approach discs. The Tour Series Phi is now available featuring an exclusive Drew Gibson design. Drew has continued his 2021 tour de force - racking up top ten finishes, feature card appearances, and ESPN media coverage. The Phi has become a staple in Drew's bag over the summer, especially for driving and long approaches.
