Nike? Adidas?
Can't imagine any of the bigger suppliers going near the Bulls this season, except ISC who could be sitting on loads of 2017 gear.
Maybe a smaller company with a license to a more well known brand. Just depends if they can deliver on quantity needed. A quick turnaround would raise the cost and maybe quality.
Replica shirts should be the clubs biggest merchandise seller by quite a margin. Would be a bit foolish not to have any all season.
