J.Lindeberg has announced their global partnership with Matt Wallace will continue until December 31, 2023.
Wallace, 30, has been a J.Lindeberg ambassador for the past three years and has spent the last two years in the top 50.
The Englishman, currently ranked 50th in the world, has won on the European Tour four times and he earned his best finish of fourth on the PGA Tour earlier this season at the Memorial Tournament.
Wallace now aims to further establish himself in the world of golf over the next few years, while hoping to fulfil a childhood dream and play his way into a first European Ryder Cup team.
The multi-year deal with J.Lindeberg will see Wallace wear the brand's apparel in all professional tournaments on both the PGA Tour and European Tour.
"I’m so pleased that I’m going to continue to work with J.Lindeberg," said Wallace.
"Every golfer wants to play in clothing they really like and feel comfortable in and that’s what I have with J.Lindeberg – it’s such a distinctive, smart but technical look.
"They continue to deliver on new styles and looks and they’re brilliant. I’m always excited to see what they’ve got planned for the next season and I’m delighted and proud that I’ll be wearing my favourite golf wear brand going into the future."
Hans-Christian Mayer, CEO at J.Lindeberg, said: "Matt Wallace has demonstrated character, determination and a love for golf that is so genuine and visible in everything he pursues.
"He is a source of inspiration for golfers around the world and we are happy to continue this successful partnership."
