Our Shadow Shifter Mens/Unisex t-shirt changes color with heat. When you touch the fabric by wearing the t-shirt or using your hand, you will see a color change.
Your shoulders will probably change color first and then when you touch the fabric it will leave a hand print showing the temperature difference.
When the t-shirt cools down the color returns to the cool color and you can repeat this transformation indefinitely.
There are three different color changing effects most popular with men, blue to white, green to yellow and grey to white. We also have three other color changing effects, purple to pink, pink to blue and orange to white which are popular with women.
