CastelliCertezza Jersey Full-Zip Jersey - Short-Sleeve - Women's

Wind-tunnel tested and Castelli certified.

Castelli touts the Certezza Short-Sleeve Women's Jersey as its most technical women's jersey, and who are we to disagree? The company developed the new paneling through a series of wind-tunnel tests, so you can be sure that it won't cause any excess drag or otherwise slow you down. On the front, highly stretchy Velocity Dry helps support your core, while stretch mesh panels on the back increase the jersey's moisture-wicking and breathable properties. At the sleeves and hem, gentle elastic bands boost the Certeza's aero fit without pinching your arms or torso, and the full front zipper helps you increase ventilation when the going gets hot. Finally, for a touch of tradition, Castelli included three back pockets for easy access to snacks, cash, or a multitool.

Great Style, Great Fit

  • Familiarity: I've used it several times
  • Fit: Runs small

Castelli generally tends to fit about the same in length and vary in width as you size up. My girlfriend is around 5'5/5'6, 110lbs, and went with small. It's snug, but still comfortable for her. Fabric quality is top notch and with the current sale prices, it's a hard one to beat if you like the style.

Great Jersey

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

I got this a few days ago. I wore it yesterday. Great fit and feel. Love how it isn't short in the torso. The pockets were okay sized, pretty deep. Seems womens jerseys tend to have small pockets so this one was better than average. I love this jersey addition to my closet. I ordered the large.(only size available) Usually wear a medium or even small sometimes. It fit me perfectly.

Castelli Does it Again

  • Fit: Runs small
  • Size Bought: Small

Fits slim. European sizing (not American). Order one size up. Castelli makes the best of the best, European sizing and quality. Can't go wrong here.

Sleek stylish lightweight jersey

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Small

Appreciate this jersey is cut a little longer than some other Castelli styles.

Castelli Certezza short sleeve jersey

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: Medium

Normally I wear size medium, but this medium runs a little small bunching up in the arm pit and not hanging down over the hips.

Sturdy and comfortable

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Small

I was initially worried that the mesh back would make the jersey flimsy and sag with any gear in the pockets -- but I was wrong! The pockets are very sturdy and do not stretch down due. They jersey fits very well and is comfortable for long rides!

fits well

  • Familiarity: I've used it several times

I have used this a few times. This cut would work great on taller cyclists (i'm 5'3- so it hits lower that usual jerseys).
