Micro Thermal System's Stomatex is a flexible laminated fabric that provides excellent thermal insulation and comfort during strenuous physical activities. Stomatex comprises a thermoformable elastic sheet covered with external and internal laminates. Flexing the material during wear stimulates the transport of perspiration through the fabric. Stomatex is available in two types: Stomatex PE, which possesses a polyethylene elastic sheeting, and Stomatex NE, which has a neoprene sheeting. Stomatex NE is stronger, more flexible, and better suited to the construction of outerwear. Stomatex PE possesses a lower density and high insulation. Stomatex fabric thicknesses range from 1 to 25 millimeters.
