The Castelli Velocissimo Gruppo Full-Zip Short-Sleeve Jersey gives you all the advantages of the pro team technology in Castelli's upper-crust jerseys at a reasonable price. Match this jersey to the Castelli Velocissimo Gruppo Bib Shorts and you'll look like you are ready to rip the legs off any rival. Balancing comfort and performance, the Velocissimo Gruppo Full-Zip Short Sleeve Jersey makes use of the Castelli workhorse fabric Prosecco Strada. It may look and feel like a classic cycling jersey fabric, but it is, in fact, a giant step forward. Unlike normal poly jerseys, the Velocissimo Gruppo jersey has a controlled stretch that means that it will conform to your contours without restricting your movements. And even though the stretch gives the jersey a natural cling, you won't have to worry about overheating since the Prosecco Hydrophylic treatment works to keep you dry by moving sweat to the outer surface where it can spread out over a larger surface area, allowing for quicker evaporation. And if that isn't enough to keep you cool, the side panels have also been made from mesh. Much of the secret of the right fit is found in how the shoulders and arm holes work with your body type. Understanding that we are all shaped differently, Castelli has incorporated raglan sleeves into this jersey since they give you the best mobility. Three rear patch pockets carry everything that you may need on an all-day outing. The full-length YKK zipper will help you keep your front ventilated, and makes it easier to take off the jersey without pouring out all the contents in your pockets if you need to take a pit stop. The Castelli Velocissimo Gruppo Full-Zip Short Sleeve Jersey comes with reflective tabs so that you'll be more visible to the cars after the sun goes down. Available in Black and Dark Blue, you'll be able to find the perfect fit with their size options running from Small through XXX-Large.
