Forbes Field was the home of the Pittsburgh Pirates from 1909 to 1970. Because the infield dirt of the park was very hard it cause baseballs to bounce wildly, so much so that announcer Bob Prince nicknamed the park “The House of Thrills.” Timeless and versatile, our tri-blend tee will quickly become your favorite tee. Made from a cotton and polyester blend, with a touch of rayon. Lightweight, breathable and has a subtle texture to give it an authentic vintage look. It's pre-laundered for an extremely soft feel, and it may shrink a bit on the first wash and dry.
