My older brothers had those in the early 90's! Coolest shirts ever. Didn't they end up being unsafe or something?
they were quite cool untill someone throws it in the dryer and kills it... but they were kinda cool....
Yeah. Today the big craze in the U.S. is hypercolor softdrinks. They got blue, yellow, red, you name it. Maybe they can come up with one that changes color as the temperature changes, like a mood ring. .
