Hunters have been taking advantage of camouflage for centuries. Fishermen have, for all intents and purposes, assumed that fish couldn't spot them from underneath the water.
Columbia, a sportswear manufacturer, claims that its upcoming, $140 solar-powered shirt will keep fish getting antsy when an angler wades into their space.
The blue shirt has a lighter pixel pattern that only appears with sunlight, but looks like any normal button-up indoors. Supposedly, the pixels break up how a fisherman will be seen from underwater.
The light-activated camo means that a fisherman could potentially wear the shirt to work after a morning spent angling.
I've never heard of camouflage for fisherman, but at least the sun-activated camo means that you'll have a regular Oxford shirt if Columbia's claims turn out to be false.
