The name Velocissima means very fast in Italian, and indeed there's a lot of speed in this jersey, even though it wasn't designed as a race jersey. It brings together three different fabrics for fit as well as comfort. The main jersey fabric is a soft 100% polyester micromesh with Castelli's ProSecco wicking treatment to keep you dry. Side panels are in a stretch mesh for ventilation and improved fit. The sleeves are lifted directly from Castelli's pro race jersey, but in this case because the four-way-stretch fabric with raw-cut sleeve endings is as comfortable as it is aerodynamic. The Velocissima Jersey is not lacking in technical details, but it was also designed to look good. The fabrics are piece dyed for rich color, and then they get a sublimated overprint for the tone-on-tone graphic over the shoulders. It's finished with construction details like the three pockets that drop below the silicone waistband for easier access, while the easy-sliding YKK® zipper makes ventilation adjustment easy.
