Activitees are work tee shirts for when you are working...
you know... For when you are doing stuff.
You know... Activity Tee Shirts.
I'm sure you get the idea.

Some t-shirts are for staff to wear, some are for the boss to wear, some are for break time.

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.

Secret Santa is not far away, so why not buy a tee shirt for someone at work!
