Gap Kids Magic Print Swim Trunks
This swim trunk uses water-reactive technology that reveals print when the fabric gets wet. So the shorts just look like plain colored shorts and then when you get it wet you get this fun surprise. Carter’s also has a style that does this. It is a really neat idea, but the execution sometimes doesn’t work as well as people are expecting. Also, if you wash these types of trunks in detergent that can sometimes interfere with whatever it is that makes the pattern emerge.
Anyway, despite my sounding so down on them, they are great shorts that are worth checking out, just be prepared in case the print doesn’t work quite as well as you are expecting.
