In fact, the new Santini collection can be mixed and matched for an effortlessly coordinated look. A four-way stretch, Polartec® Delta™ fabric has been used in four pieces of this new collection. The Santini Delta Pietra jersey and the Delta bibshorts (men and women’s options available). Polartec's Delta™ fabric is perfect for use in sportswear designed for high intensity activities such as road cycling. It has been designed to [harness the cooling properties of sweat](https://www.polartec.com/fabrics/base/delta) but without the annoying cling. The specialized knit construction uses hydrophobic and hydrophilic yarns for more advanced control of moisture dispersal. The hydrophilic (water-loving) yarns sit close to the skin, wicking sweat to the external, hydrophobic (water-hating) yarns which hold onto it just that little bit longer, so, harnessing the body's own cooling process. These patent-pending radiating knit structures keep you cooler in hot conditions by increasing airflow to dissipate heat. No cling just comfortable cool. The coordinated bibshorts – Karma Delta bibshorts for men and Tono Sfera bibshorts for women – also use Polartec Delta fabric which is located in the braces. This ensures the technical abilities of the jersey are not hindered by the bibshorts. Together the two pieces of clothing work in a unified fashion to keep the wearer cool and comfortable throughout their ride. [Visit Santini Cycling ](https://www.santinicycling.com/) Share.
