Pontetorto stands out for the use of extremely fine polyester yarns in the production of Micro and Supermicro fabrics suitable for the first and second layers. The fibers used can reach a fineness below 0,5 den. in the case of Supermicro and after the finishing procedures the fabric is compact, uniform in volume but extremely light. Numerous hollow air spaces create an insulation effect with high thermal efficiency, for this reason the fabric is always warm when in contact with the skin. Comfort and lightness together with considerable thermal properties guarantee a technical product ideal for different sport activities but also suitable for everyday life style clothing.
