Sun-Through Swimwear for the Effortlessly Golden
For those who dream of a flawless, even tan without the undignified faff of repositioning every five minutes, Smarttan is here to help. Designed in Estonia by a family who knows firsthand the benefits of sun exposure, Smarttan’s innovative swimwear lets the sun do its work—safely and stylishly.
More Sun, Less Hassle
The idea behind Smarttan was born out of necessity. When one member of the family found that sunlight was the most natural relief for psoriasis, it became abundantly clear that ordinary swimwear was standing in the way. Finding high-quality sun-through swimwear was a near-impossible task—so they created it themselves.
