Puro is the right name for this jersey. Clean design, useful reflective details, attention to detail. It is slightly lighter than the Espresso or Entrata jerseys, making it ideal for early autumn or late spring days, but also in winter when adding a warmer baselayer. It is special because the fabric is made in Italy. The horizontal line effect on the outside comes from a kind of ribbed fleece inside, which creates air pockets to provide more warmth. The polyester yarns ensure breathability. Very soft to the touch, it has excellent elasticity for a snug fit without tightness. Finished just as you expect: YKK® Vislon® zipper for easy on-the-fly adjustment, three rear pockets, and 360° reflective detail.
