OG Medium Phi - Thought Space Athletics "Birdie Brigade"

3/4/0/1  *Limited run of TSA Birdie Bash stamped Phi!  Storage wear possible with this plastic type.      

The Phi is a beadless putter that has less fade than the Penrose, providing a stable enough putter to handle headwinds and handle those approach shots with excellent glide. This makes for a great driving putter and a dependable putting putter.

OG Medium is a semi-firm blend of the OG plastic with only slight flexibility and a good feel and grip.
