Inspired by the USA v. Mexico matches over the years, Bumpy Pitch has teamed up with Nike on The Rivalry Tees. From BP:
Th idea behind this rivalry pack has always been about exploring the rich rivalry between the US and Mexico. The shirts feature elements of domination over one another, but also touch on the element of respect for the rivalry and an understanding that we need our fiercest rivals to always inspire us to be greater.
Available at the Bumpy Pitch shop.
