This shirt is an inside joke. Our co-founder, Harold “McGoo” McGruther created an infamous BMX mail-order business before there was an internet and it was called Mental Jimmy’s. This one is for all the old 20” riders out there. 100% pre-shrunk 6oz cotton tee is detailed with hand-screened water-based inks, woven clip tags and the irritating collar tag has been replaced by a screen-printed label. We consider this the perfect T-shirt blank – it's got a buttery feel and is thick enough to be durable, but not a baggy old man shirt. It's a true regular-fit, not a super thin slim-fit. Printed in the USA.
