Tumbler Mug - White to Purple

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 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!
