I really like the look and feel. I got the large based on reviews and glad I did. I am usually medium but this fits a little snug. I am 5' 10, 160lb. The red is brilliant and the graphics are cool and understated. The jersey is light and good in the very hot Florida summer. The torso and waist section is a bit loose but I think the medium would be too tight for me in the shoulders. The material breathes well and super light. Overall great jersey!
I'm in my late 50's and out side of the occasional century, I ride for fitness and weight control. As cool as those form fitting jerseys look on the Tour de France riders, it's not necessarily my style. The Castelli Prologo is just loose enough to feel good and on a long ride, comfort is everything! My perfect jersey!
Used for short to medium length rides. The fit is competition,would prefer a slightly larger fit. The quality appears to justify the price
Used for casual riding. The materials and design are the best I have owned in 40 years of road riding. Wish they offered more products in a non-race fit
