Saints have announced that their kit for next season will not be made by adidas.
The current kit manfacturers will not be producing the new kit for next season, with further details yet to be released.
A club statement said: "Following months of discussions at the end of last year, the decision was made at the start of December 2013 that the Club would terminate its contract with its Official Technical Supplier, adidas.
"In February and March of this year, the Club worked hard to repair the relationship with adidas but, despite these healthy discussions, it has become clear that, due to the short lead times involved, adidas were unable to produce a Southampton kit in time for next season.
"As a result of this the Club has had to find an alternative solution, and we will be unveiling exciting news regarding our 2014/15 kit within the next couple of months."
