The Prologo 3 Sleeveless Jersey is identical in every way to the standard version of the Prologo 3 jersey sans sleeves. Careful attention was paid to the cut outs for your arms. They are double stitched, hemmed flat and anatomically shaped. This means they are completely natural feeling and no material bunching will occur. When the temp rises it's hard to beat a sleeveless jersey and the Prologo 3 is as good as it gets.
The main panels of the Prologo 3 are constructed of Castelli's proprietary dual-layer Stratus fabric with the magical Prosecco treatment. The dual layers of the Straus work in tandem to keep you dry. It works like this: You sweat and perspire onto the single layer of Stratus that is next to your skin. This moisture then gets transferred to the outer layer. The layer next to your skin is now dry again and the moisture in the outer layer dries out quickly from exposure to the elements. Simple and effective. The Prosecco treatment quickens the drying process by spreading perspiration and moisture over a larger surface area within the fabric on the outer layer of Stratus.
All of the panels are anatomically correct, so the jersey fits well. A note about the fit, the Prologo 3 has a bit more relaxed cut than the Aero Race jerseys. Comfort is king with the Prologo 3, but by no means is it baggy and loose. It is still a fitted jersey. Other details include the full length YKK zipper that is easy to use and helps regulate body temperatures. 3 large pockets with one small zip pocket in the rear take care of on-bike storage. Choose size and color.
