The secret is the new MICROSOL fabric, a gas infused polyester fabric that lets sunlight through at about the same rate as a medium level sunscreen. This unique patented fabric is made with a special knitting technology that creates millions of tiny pores in the fabric which allow approximately half of the sun's light to pass through. This means you get a natural suntan, right through the fabric, about as fast as you would with a medium level SPF sunscreen.
The MICROSOL fabric technology in our COOLTAN swimsuits allows air to pass through the fabric, allowing your skin to breathe and the wick moisture away to keep you cool all day long. Because the material is so light and thin, it allows you to pack more when traveling and it also dries up to 3x as fast than any other fabric!
