Coolmax is a synthetic fiber developed by the American company Invista, which has already brought several advanced innovations to the world of synthetic materials. It is made of a unique hydrophobic 4-channel fiber for better moisture wicking.

This material is known and respected for its ability to dry and wick moisture very quickly, which is why it is most often used as a material for underwear and socks, especially of a sporty nature. During active movement, Coolmax does not soak up moisture, but continuously wicks it away, so that the material remains dry and its functionality is not compromised as with cotton. This prevents not only discomfort but also the potential formation of blisters. In addition, Coolmax fiber is very soft and pleasant to the touch, is resistant to odors or mildew, does not abrade, and is very easy to maintain.
