Grindhouse University. Come here and get schooled. A 4.5 ounce 100% cotton tee-shirt with a removable tag. This shirt is comfortable and breathes exceptionally well ( which is important for the summer heat ). The cotton is “ring-spun” which makes the tee shirt softer and more wearable than your average tee. We guarantee you’ll be comfortable in this shirt. This shirt is Memphis-ready, Grizzlies inspired, and will likely make you far cooler and more attractive than you would be if you weren’t wearing it. The shirt sizes are listed as men’s, but this is considered a ‘unisex’ style shirt, and features a slightly slimmer cut. It is pre-shrunk.
