Be Sol Smart™ and stay refreshed while having fun in the sun with Del Sol’s world-exclusive, color-changing bottle, part of our evolving Sol Smart™ Collection of color-changing products.
Not only is this stainless-steel, vacuum-insulated bottle designed to keep your liquids cold or warm, but it’s also engineered with Del Sol’s innovative Spectrachrome® technology that changes the bottle’s color according to the intensity of the sun’s UV rays.
The more intense the color changes on the bottle, the higher the intensity of the sun’s UV rays. When you’re outside having fun in the sun, simply refer to the strength of the color-change on your Del Sol bottle to then take action against too much sun exposure. Like two bottles in one! One color inside, another color outside!
Experience Del Sol Color Change
Much like a flower that blooms when exposed to sunlight, Del Sol's products change colors in the sun using their proprietary Spectrachrome® technology.
Spectrachrome® molecules in the products shift to colors visible to the human eye when exposed to UV sunlight.
Del Sol's Spectrachrome® formula for color change was developed from a concept originally researched by NASA for use in space.
