How do Shadow Shifter Adult shirts work? Shadow Shifter Adult Shirts may seem like magic, but there’s actually a scientific explanation behind their color changing abilities. At the heart of these innovative shirts is a special thermochromic dye that reacts to temperature changes. When the fabric is exposed to different temperatures, the dye undergoes a chemical reaction, causing the colors to shift and transform. The thermochromic dyes used in Shadow Shifter T-shirts are specially calibrated to change when you wear the t-shirt and touch it. You must wear it to make it change color. « Just like the ones back in the ’90s. Very nice.  » msdodie – Reviewed in the United States on May 11, 2023 How to take care of your Shadow Shifter shirt 1.
