I ride for enjoyment and I prefer to stay dry and comfortable. I saw this jacket last year and it looked good to me so I found out how its made and heard a lot of good things about the brand. I have been adding better visibility to my biking outfits and I bought this in the cayenne color which I think really holds your attention and I feel safer when I ride with it. I saw reviews which were mostly very favorable but I saw a few in which the writer was disappointed not to have side pockets. I also would prefer that but the pit zips open to the inner layer so wear a base layer with side pockets and reach inside to use those pockets, problem solved. It really is a great jacket.
Although small fit me snug but fine for my other 6 pairs of various Castelli bibs, I could not come close to getting these on in small, so this rating is only a heads up on fit - I have not worn the bibs. They did seem very nicely made.
We've come a long way from riders shoving a newspaper in their jerseys before chilly descents. If it's too warm for a full-on jacket, but still a little blustery and nippy, this baselayer under a long-sleeve jersey is the business. Kept me comfortable into the mid-30s. The vented pits and breathable back panel are good at preventing overheating. Size-wise, I wear a medium in Castelli jerseys, but found the small baselayer to fit better under other clothing than the medium.
I recently picked up one of these jerseys to add another choice for my spring and summer cycling wardrobe. This jersey has high-end feeling fabric, with slim arm gripping panels and a nice reflective piping on the tail. The cut is definitely race fit, so make sure to go one size up from your normal Pearl Izumi sizing. The pockets are the right size, and there's enough room through the shoulders and torso to accommodate a decent variety of body types. Overall highly recommended.
