A dull 0-0 draw between hosts France and Switzerland on Sunday (June 20) took an amusing turn when a series of wardrobe malfunctions prompted an apology from sports apparel maker Puma.
Four jerseys - all worn by Swiss players - tore easily after some gentle tugging, in what has already been dubbed "jerseygate".
New Arsenal midfielder Granit Xhaka had to change his shirt twice; forwards Breel Embolo and Admir Mehmedi were also not spared.
Playmaker Xherdan Shaqiri, in an interview with Swiss newspaper Blick after the game, evidently saw the funny side of things.
"I hope Puma doesn't produce condoms," quipped the Stoke City star.
The manufacturer, which CNN reported as the tournament's third biggest kit supplier, swiftly responded to the fiasco with a statement addressing the supposed flimsiness of the jerseys.
"Our analysis of the Swiss Home jersey (made of an elastane and polyester material mix) from Sunday's game shows that there was one batch of material, where yarns had been damaged during the production process, leading to a weakening in the final garment," Puma said.
"This can happen, if the combination of heat, pressure and time is not properly controlled in the manufacturing process."
Puma added that the defective material was used in a limited number of jerseys.
It was not a good day for the equipment makers as adidas also suffered some embarrassment when one of its much-vaunted Beau Jeu balls burst following a challenge by Swiss midfielder Valon Behrami on French striker Antoine Griezmann.
Griezmann reportedly put his studs in the ball, which retails at £105 (S$207 ).
In a statement, adidas said it was looking into the incident and stressed that this was a rare occurrence.
"The reason for the tear has not yet been identified but Beau Jeu has been widely praised by respected experts for its contribution to the exciting start to the tournament."
