37.5® technology is a patented technology developed by Cocona that uses body heat to evaporate moisture. 37.5® active particles have two unique driving forces. First, they use the force of electrostatic force to let moisture escape from the skin. Second, they absorb the infrared energy naturally released by the body and use it to heat particles and accelerate evaporation.

37.5® technology can keep the micro-climate on the skin surface at the optimal relative humidity, so that the body can maintain the ideal core temperature more effectively.
37.5® active particles are made of natural materials. Certified by the Heinstein Institute, the 37.5 fiber meets the criteria for harmless and hypoallergenic skin.
37.5 active particles will be permanently embedded in the yarn and will never be washed off or invalidated.

Sustainable products have become a hot spot in the current market, so 37.5 technology has also developed the recycle version. Recycle 37.5® products have the same performance as the original products.
