Does it need to be a Tshirt ?
Polo shirts are a lot more comfortable I find, and I can't get Himself and Son2 out of them too.
Polos also look a little smarter, more of a staff uniform thing, as comfortable as T's but you look less like you've just stepped out of the boonies. (says me sitting here in a green T-shirt)
