The "Power Top" shirt design was screen printed by Burly Shirts in the beautiful state of Maine, USA. Printed on a 100% cotton T-shirt.  White ink on deep forest green shirt.

The exact brand/cut of T-shirt that this design is printed on is partly dependent on the size.  The vast majority of this shirt design is printed on the Next Level Men's Cotton Crew T-shirt, which is a 100% combed ringspun cotton fine jersey, pre-washed with a tear-away label.  This style runs a little small, and is a more fitted cut in the arms.

2XL size is printed on the Hanes Nano Tagless Men's T-shirt, which is 100% cotton pre-shrunk lightweight jersey knit.
2XL in Hanes Nano: Chest 50-52", Length 32.5"

3XL sizing is printed on Next Level 100% Cotton Crew:
3XL: Chest 53-56", Length 33"
