Backbone is an aerodynamic, ergonomic, lightweight and breathable jersey with very high performance. It is made of three different types of fabrics. The front is made of highly stretchy Sensitive® Minicheck for maximum comfort, while the back is made of Polartec® Power Dry® fabric with a strong mesh effect. The structure of the back fabric allows items to be stowed in the pockets without stretching, thus avoiding uncomfortable unbalanced weight on the back. Sleeves are made of 3D laser-cut tubular fabric for maximum grip without pinching. Polartec® Power Dry® is a two-component fabric made with a hydrophilic inner side whose fibres are arranged vertically to allow body moisture to be wicked away and transferred to the outside. The outer surface releases accumulated sweat very quickly, allowing for fast drying. Continuous evaporation regulates temperature in warm and temperate climates. The fabric also has a special treatment that makes it anti-odor and anti-bacterial, and it is also recycled.
