The talented Australian striker lost his battle with cancer in April last year, cutting short a promising career, which the Hammers plan to pay tribute to through the foundation.
The idea of DT38 is to raise awareness of testicular cancer to help sufferers detect the problem early while remembering Tombides' legacy and West Ham manager Sam Allardyce feels it is a great cause.
"There's far too much publicity on the not so nice side of football and not enough publicity about the outstanding work that goes on behind the scenes, particularly in the community, the foundation, things that have gone on from Dylan's legacy," he told Fox Sports.
"From Dylan's family's point of view, it's nice to see he won't be forgotten at West Ham.
"The bravery of the lad impressed me the most; he was fighting back to play football more than anything else.
"He should be an inspiration for all the young players who played with him, or were younger with him, to fight and make a career."
