The shirt, predominantly blue with black and white detail on the sleeves and shoulders, is now available in the United Megastore and online via United Direct.
David Moyes' side will wear the kit during daily training sessions at the Aon Training Complex. The training shirt is just one of the key pieces in Nike's new training collection, which also includes training shorts, training jackets, matchday warm-up shirts and sideline jackets.
Designed by Nike and utilising much of the same state-of-the-art technology that's incorporated in the playing kit, the training shirt will help Moyes' men produce performances of the highest level as Manchester United aim to retain the Barclays Premier League trophy in 2013/14.
