Solar active t-shirts are clothing items that change colour when exposed to sunlight, using special dyes or inks that react to UV rays. They can be a fun and creative way to express your personality and style

Solar active t-shirts work by using photochromic technology, which means that the molecules of the dye or ink change their structure when they absorb UV light. This causes them to reflect different wavelengths of visible light, resulting in a colour change. The colour change is reversible, meaning that the t-shirts will return to their original colour when they are away from sunlight.

• Solar active t-shirts are designed to last for a long time, as long as they are properly cared for. The colour-changing effect will not fade or wear off over time, unless the t-shirts are exposed to extreme heat, chemicals, or bleach. To prolong the life of your solar active t-shirts, you should follow these tips:
  • Wash them in cold water with mild detergent.
  • Do not use fabric softener or bleach.
  • Dry them on low heat or air dry them.
  • Do not iron them or dry clean them.
  • Store them in a dark and cool place.
