Everyone has seen the sunglasses that darken automatically when you go into sunlight. Well, now you can have clothing that changes color as you move out of the shadows, too.

With T-shirts, hats and visors, shorts, flip-flops and more, Del Sol clothes are sun activated. The basic plain two color item, say blue on white, all of a sudden in the sun light has pink, yellow, green and purple hues. They just come alive. They are beautiful.

Del Sol's special formula for color-change technology was developed from a NASA concept using Spectrachrome® Crystal Dye. The Spectrachrome® crystal reveals color upon irradiation by ultraviolet waves like sunlight.

In technospeak, the shifting or "twisting" of the dye is a molecular excitation transition. The cloth does not actually "change" color; rather, its colors become visible to the human eye.
