The 28-year-old Dutchman, who won -90kg gold, is raising money for KWF Kankerbestrijding which funds cancer research in the Netherlands.
“All the money I raise with it will go to a cancer foundation that is very close to my heart. I lost my dear grandma last year and 12 years ago I lost my best friends mother Josephine.
“They where very special people! And every time when I go on the mat I think about them to get extra power.
“With this gesture I want to take a away to powerless feeling I had when they where suffering so much!”
The current bid at the time of publication is £895. There are three days left for the auction for the 175 size white judogi which will go down as one of the legendary items of Dutch judo memorabilia.
