The shirt is  made from good materials, & might be considered "heavy" for hot summer wear. My husband is a 2XLT normally (6'3" 250) so I wasn't sure if it would remain in his size, so I just machine washed cold hung dry until slightly damp, then air dried. Three washes so far and he still likes the fit.

I bought this at a store in the mall known for gag gifts & black light posters in the 80's, which now has moved into the garment business. It's the same shirt, with the  same iron on.
