A Bloc Full-Zip Jersey

In cycling parlance, going À bloc means giving it all you have or riding as hard as you can. Think a last-minute attack close to the finish where you're burning up your remaining matches in hopes of a race-winning move. The A Bloc Full-Zip Jersey from Castelli is a fitting name for a jersey that's got your back when you're going all out.

Castelli constructs the main body of the A Bloc from ProSecco Micromesh which breathes extremely well to keep you drier. Mesh side panels further boost ventilation so you stay cooler on those fast group rides and if it's still too warm, a full-length YKK Vislon zipper lets you easily dump heat. Final material details include the Velocity Rev2 fabric on the sleeves offering a close-to-body fit for better aerodynamics and raw-cut endings for a smooth transition to your skin.

The jersey is finished off with an extended drop tail for more coverage and 3 rear pockets for hauling snacks and tubes and reflective piping helping increase your visibility in low light.

Looking for matching gray castelli bib shorts. Can you point me in the right direction please

Very Relaxed Fit

  • Familiarity: I've used it once or twice and have initial impressions

This is not your typical Castelli skin-tight fit jersey, which can be good or bad depending on what you want. In my regular Castelli size (L) the zipper area bunched up when riding, but did not flap in the wind. Quality of the material and zipper seem excellent, but the neck area is oddly large, possibly to help with ventilation. I expected the slight bagginess to have a negative impact at higher speeds and in the wind, but it did not appear to. I personally prefer a tighter form fit from both an aero and aesthetic standpoint, but as long as you know what you're getting in this it is a solid jersey.

Not a tight Castelli fit

  • Familiarity: I returned this product before using it
  • Fit: Runs large
  • Size Bought: xl

FYI: This is a "standard" fit. It is not a race fit. If you love the fit of the race Castelli, you may not like this cut. Was tight in the chest and arms, but loose in the waist. I normally wear a XL in their aero and climber's jerseys. I decided to not exchange for a large or medium for fear the fit would be too tight in the chest. I love the color, but returned because of the fit.

Great simple jersey

  • Familiarity: I've used it several times

I like the color blocks on this one and the fit is spot on too. the sleeve length gives a look of a more professional jersey but the body is not too form fitting to feel like you are racing a stage. great everyday choice. Note that Castelli does feel a slight bit short in the front for taller riders

This jersey feels great and looks awesome with the vibrant colors. I have worn it several times and could not be happier with the purchase. I ordered the blue jersey in size XL. As soon as you put it on, the jersey feels soft and cool.

my new orange castelli a'bloc jersey

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

wore this for the first time today. fell in love with it when i put it on. very soft texture, great fit, beautiful colors. only concern i had was the raw cut sleeves. no problem.they fit great, didn't slide up my arms like some short sleeves will do. wore it on a 45 mile ride on a cloudy day with the temperature around 60 degrees.was comfortable the whole time. even the zipper was kind to me and functioned like it should. my wife makes fun of me about my zipper problems. this is a great jersey.
