casey shirt 

A gym shirt with the sleeves cut-off creating large arm holes often encompassing much of the side down to the abdomen. In many cases, this includes exposing the nipple. Worn by tough men lifting weights.

Man, this casey shirt is awesome. It really lets my pecs breathe.

I can't believe they wore their casey shirts to the meeting. How unprofessional.

Casey and Eth's T-Shirt Company 

A top quality Canadian designer brand. It's rumored they produce only 50 t-shirts a day which would explain the well-rounded price of them. One shirt can go for hundreds of dollars online.

I just copped a new Casey and Eth's t-shirt from Casey and Eth's T-Shirt Company.
