No special shirt needed. Have your cleaner do a fold for you. When you pick up your cleaning instead of getting a bunch of shirts on hangers, you get a box with 4 to 5 shirts per box that are prefectly cleaned and folded around a piece of cardboard and individually wrapped in plastic....ready for the suit case.

I have two blue and two white shirts that are polyester and i wear them on travel days if it is going to be a long flight...they are wrinkle free withe the addes bonus that ill burn faster and extra crispy should the plane im flying on happen to crash.
