COOLMAX is a specially engineered type of polyester exclusively produced by Invista, an American textile corporation. This polyester fabric consists of fibers that are carefully engineered to wick moisture and allow the passage of heat.

Experimental tests have shown that the drying speed of COOLMAX is significantly faster than that of ordinary functional yarns, with the effect being approximately twice that of cotton! Moreover, due to its larger surface area, the opportunity for air to pass through also increases, allowing the skin to remain dry and comfortable all the time. When the body is in motion, it can naturally regulate temperature and humidity, avoiding excessive heat or rapid cooling.
