Lydia Ko × GOLF Partner
Proto Concept irons were Lydia Ko’s primary choice when she won the 2022 Gainbridge LPGA at Boca Rio on January 30. 
It started as a suggestion from her personal club fitter but is now what Lydia Ko, 24 year old New Zealander and No. 3 ranked player, prefers. Proto Concept is our original brand and we are proud and honored to sign with her for the rest of 2022!

A word from our brand producer and managing executive officer of GOLF Partner, Yasufumi Kawasaki, “Proto Concept Golf and GOLF Partner USA are thrilled that a player as accomplished as Lydia Ko has decided to play Proto Concept irons in her pursuit of playing the best golf she can”.

”Lydia began playing Proto Concept irons because she is comfortable with them and believes they will help maximize her performance. We are happy to sign her to an endorsement contract after she made that decision.”
Ko will represent a GOLF Partner logo on her bag, umbrella and headcovers! For image and likeness, we will have the rights to her name through both GOLF Partner and Proto Concept
