Good Quality

Well made and comfortable shirt. I use it for exercising at the gym and usually get a laugh or two. So far no laughs during exorcising.


Well made, good quality fabric and print, but for the love of all that is dear and fluffy, *size up*, because it will shrink when you wash and dry it. If you never ever intend to put it in so much as warm water or a warm dryer, fine, but we’re not about cold-wash hang-dry life over here. Husband definitely loves it and I love the way it looks on him (fit well-built dude), but I think he would have preferred it a little looser. I sized correctly according to their charts. Oh well! Now we know for next time.

Thanks for listening!

Our family of four non-tank wearing exercisers now each has the sleeved variety of Exercising Demons - Just in time for the holidays. Nicely printed and good looking shirts. We are pleased.
