Sublimation - yeah they look cool, but their subtlety is lost on many non-OzSTOC members, I've been asked if I've joined a lawn bowls club.
Odour - not a problem for me, not sure if it's a concern for the company I keep though. And this is not the place for smart-alecky comments on that matter.
Have many, many cotton (probably a blend) T-shirts, no problems with shrinkage, and they don't need ironing (washing machine to clothesline to drawer to me).
Pocket - yes handy, but (I think it was the Mudgee polo), without some reinforcing, the pocket went outta shape and looked very sloppy and untidy - so bad, it went to the OpShop.
T-shirts for me - got many years wear outta the orange Ballarat, maroon (previous Toowoomba), navy (Mannum) and beige / nude (Mudgee) and T's. The orange and maroon have both gone to meet their maker; navy and beige get regular use
