To Manchester United players, the training jersey is more of an everyday item than a tee or hoodie. That's why adidas designed this training jersey for equal parts style and performance. The smooth fabric keeps you dry, whether you're on the pitch or off. With a club crest in front and a signoff in back, it shows your support whether you're coming or going.
