I have no idea if Pirates were with Adidas in the early 90s so I can't say if this is retro themed. Also, I can't think of another team that will be using this template for their kits so in that sense, Pirates fans must be pretty happy that they've not been lumbered with a generic teamwear template.
A throwback to the time when adidas finally went mad and lost all sense of taste and class. It's just a big adidas logo. Remember Liverpool wearing a red & white version of this? It was nasty back then and dragging the same design out the bin for now doesn't impress anyone.
