Activitees are work tee shirts for when you are working…
you know… when you are doing stuff.
I’m sure you get the idea.
You probably wouldn’t wear one of these when you are strutting your stuff at the local disco, but you might wear one on a Sunday morning when you are lounging in front of the sofa, remote control in hand, trying to find something not too taxing after a night out on the sauce. Wear them with pride, the pride in knowing you are not at work.
