UndisputedPremium cottonBlackS to 4XL
The essentials: on 18 May 2024 in Riyadh, Usyk beat Tyson Fury and became the first undisputed heavyweight champion since Lennox Lewis in 1999 — a twenty-five year wait. That is the word this tee carries: UNDISPUTED, under a photograph of the fighter with his fists clenched. Premium cotton 180 gsm, crew neck, heat transfer print. Black, 7 sizes S to 4XL, €29, free shipping.
One word, and it names a status nobody had reached at heavyweight in a quarter of a century.
What undisputed means
A boxer is world champion as soon as he holds a belt. He is undisputed when he holds all four: WBA, WBC, IBF and WBO.
It has become rare because each sanctioning body imposes its own mandatory challengers and its own calendar. A champion who declines an imposed fight is stripped: belts scatter faster than they gather.
At heavyweight, Lennox Lewis had been the last, in 1999.
Usyk: two divisions, undisputed three times
- 2018 — He gathered all four belts at cruiserweight, at the end of the World Boxing Super Series.
- 18 May 2024 — In Riyadh, he beat Tyson Fury on a split decision and became undisputed at heavyweight. He is the only fighter in history to be undisputed in two divisions in the four-belt era.
- 19 July 2025 — At Wembley, in front of 90,000 people, he stopped Daniel Dubois in the fifth and became undisputed heavyweight champion again. Nobody had been twice undisputed at heavyweight since Muhammad Ali.
He has beaten Fury twice, Anthony Joshua twice, Dubois twice, and has never been knocked down as a professional.
The 17 on the trunks
The number visible on his waistband is his lucky number: Usyk was born on 17 January. He has worn it on his kit throughout his professional career.
What it looks like on
A three-tier composition, over the full height of the chest.
At the top, OLEKSANDR USYK in large white capitals, slightly arched. At the bottom, UNDISPUTED in textured capitals, stencil style.
At the centre, a photograph from the waist up treated in high-contrast black and white: Usyk bare chested, mouth open mid-shout, fists clenched in white gloves, a chain with a cross at his neck. On the waistband of his trunks, the 17 inside a rectangle.
The treatment is posterised: the shadows go to solid black and merge into the fabric, and only the whites draw the body.
Premium cotton, crew neck, short sleeves, straight cut. Plain back.
