Our Switch trunks are Thermochromic, meaning they are temperature sensitive. The color will switch from warmer to cooler water temperatures or vice versa.

The outside temperature will also have an effect on the trunks. If you are in warm weather and dip into warm water, the color change will not be as drastic than if you were to go from warm weather into cool water.

Care Instructions:

Remember, the technology is temperature driven so it is especially important to wash with cold water and Do Not machine dry the swim.

Do not hang to dry in the Sun.
