There's no time to explain, Time Hero -- get in the Time Device!
Retro Ride is printed on Heather Imperial Purple BB401, American Apparel's insanely comfortable 50/50 shirt. (Ladies: BB301, 3X-5X: Gildan 8000, 6X: Hanes 5250). The two-color discharge print is courtesy the former Spray 4 Pay proprietors at Forward, with amazingly soft inks that blend right into the fabric.
This is the kind of shirt which gains a little character with each wash -- just make sure to turn it inside out before washing!
