Andy Murray signs four-year £15m Under Armour kit deal

Andy Murray will wear Under Armour branded clothing from the start of 2015 after agreeing a four-year deal with the American brand worth a reported £15m.

The British No.1 has parted ways with Adidas after five years with the leading manufacturer and becomes the latest high profile addition to Under Armour's portfolio.

Murray will wear the kit for the first time at the Mubadala World Tennis Championship exhibition event in Abu Dhabi where he faces Feliciano Lopez in the quarter-final before a possible meeting with Rafael Nadal.

"I am very honoured and excited to be joining Team Under Armour and to help them tell their story globally," said Murray. "They are committed to providing innovative apparel, accessories, and footwear, with an unmatched focus on training and performance."

Though Under Armour are providing all of Murray's kit from the start of 2015, the two-time grand slam champion will continue to wear Adidas Barricade shoes for the first half of the season until the company develops acceptable footwear for the Scot.

The world No.6 joins skier Lindsey Vonn, United States Ryder Cup star Jordan Spieth and American football legend Tom Brady on the Under Armour roster.
