Half-Zip Jersey with 37.5® Technology

This innovative double-knit Jersey has a technical look on the outside and a particularly breathable brushing on the inside, but the main feature of this knitted fabric is the 37.5® technology, which allows for dynamic thermoregulation, keeping the body at the ideal internal temperature of 37.5 degrees centigrade, creating a microclimate close to the skin with the right level of humidity of 37.5%. This technology uses active particles based on volcanic sand that also absorb infrared light (IR), transforming it into energy: when the athlete is hot, the active particles incorporated into the material use the body's energy to cool. When the athlete is cold, the active particles retain the body's energy to help keep him warm.
