The two players have joined Wilson's growing list of golfers which includes John Augenstein, Kevin Chappell, Quade Cummins, Padraig Harrington, Brendan Steele, Kevin Streelman, Martin Trainer and Kevin Tway and LPGA Tour player Sophia Schubert.
Wilson also has a deep list of DP World Tour players in their ranks such as Marc Hammer, Alexander Knappe, Benjamin Herbert, Joakim Lagergren, David Law, Hurly Long, Craig Mackie, Jack Senior, Paul Waring and Andrew Wilson.
Kisner, a four-time winner on the PGA Tour, made five top-10 finishes including a runner-up finish at the WGC Match Play and a third-place finish at the Sony Open.
The 38-year-old also made his second appearance for the United States Presidents Cup team last year. He may only have delivered half a point, but it helped Davis Love III's side win for the ninth time in a row.
"I am excited to be partnering with Wilson Golf. Wilson is a brand I’ve always respected; rooted in heritage but always looking for new ways to evolve," said Kisner.
"I’m quite particular about my equipment, and the clubs that I’ll be putting into play after extensive testing are second to none."
Mullinax is set to make his debut for Wilson at the Sentry Tournament of Champions in Hawaii this week, following his win at the Barbasol Championship back in July.
This began a good run of form for the 30-year-old who reached the second stage of the FedEx Cup Playoffs. He will tee it up with J.J Spaun in the first round at Kapalua on Thursday.
"As Wilson continues to grow in golf, we are excited to have Kevin and Trey join the Wilson team," says Tim Clarke, President of Wilson Golf.
"More players are putting Wilson golf equipment into play on worldwide professional tours every week, and we are excited to support their efforts in achieving their goals."
