Auto-Sensor® is a nanotechnology fabric with patented features that has been developed by Ventex. The fabric itself is a breathable three layer polyester (80%) construction with polyurethane spandex (20%) for 4-way stretch comfort.

The two primary functions of Auto-Sensor® are moisture transport and temperature regulation. Hydrophobic and hydrophilic fibers suck perspiration moisture away from the skin and disperse it across the exterior fabric face for evaporation.The temperature regulation function maintains the next-to-skin temperature of the garment at a constant comfortable level keeping the athlete warm in cool conditions and cool in warm conditions. Auto-Sensor® fabric is also antibacterial through application of silver dioxide fiber technology.
