What does COOLMAX mean? 

Like Lycra, COOLMAX® is the brand name of a patented fiber and COOLMAX® fiber is owned by Invista, formerly known as DuPont Textiles and Interiors. Invista develops and manufactures other fibers such as nylon, spandex, and cotton. 

What is COOLMAX fiber made out of?

COOLMAX® is the result of blending multiple different types of polyester fibers. Unlike other fibers, COOLMAX® fibers are not circular or round. Rather, they're shaped with grooves or divets lengthwise along the fiber. It's manufactured in a way that allows moisture/liquid to be drawn away quickly from the skin. The grooves or divets in the fiber wicks moisture through the fabric to a wider surface through capillary action. This capillary action allows for a faster evaporation rate, keeping your feet dry and cool.
