Cabela's ColorPhase Color-Changing Camouflage Clothing
Camo clothing that changes with your surroudings - for real! AS the tempurate changes, so does the temperature-activated dye in the clothing. (And holy crap that's a lot of C's in the title.)
(And could we get any more C's into the title of this product? Yes, we could've but we werre running out of room.)
When it's warm out, the vivid greens come out in the camo. When it gets colder, the greens change to shades of brown (i.e. for fall).
Cabela's ColorPhase technology has two varieties: woodlands and western, each with it's own warm and cold phases.
