Pro Issue Short-Sleeve Baselayer
The days that you feel a slight chill when you step outside are often the toughest to dress for. The sunny skies suggest you'll quickly warm up, but you don't want to spend the first several miles of your ride fighting off a chill. For rides like this, grab Castelli's Pro Issue Base Layer. This lightweight polyester crew-neck top fits under your jersey and helps facilitate moisture transfer from your skin to the surface to regulate your body temperature. It won't be as insulating as Castelli's Flanders base layers, and it won't cool you off as much as Core Mesh, but it will do a little of each to keep you comfortable on the rides that are difficult to categorize.
As far as construction, Castelli eliminated more seaming in this latest version of the Pro Issue to enhance comfort, and it widened the collar to give it a more streamlined fit under aero jerseys. The flat waist hem helps prevent chafing or irritation by laying smoothly against the skin in shorts, and according to Castelli, the base layer functions best in temperatures ranging from 59 to 77 degrees Fahrenheit.
- Late-spring, early-fall professional base layer
- Specifically designed mesh fabric moves moisture away from your skin
- Upgraded seams at shoulders provide a more comfortable fit
- Wide collar goes well with current generation aero jerseys
- Flattering waist hem lays flat under bib shorts
- Castelli's roots in performance cycling textiles date back to 1910

Vital piece of kit for cool days
- Familiarity:
- I've put it through the wringer
This is my first cycling base layer that isn't for winter. I was skeptical prior to ordering, but have become a true believer. I just did a Century ride where the temp started at 61 degrees and warmed up to 77. Not once was I cold OR overheated. I did a fair amount of climbing and would unzip my jersey half way for the ascent and then zip it back up for the descent. Absolutely perfect for this temperature range. For sizing, I wear an XL (5'10 185lbs) in Castelli Jerseys and an XL in this was perfect.

Excellent quality light base layer
- Familiarity:
- I've used it several times
I ordered knowing that Castelli makes quality items and as expected these are no different, started with 2 and have 2 more on the way. I'm 5' 10", 165lbs, 37 chest and Large is perfect. I wear one size up (Large) in Castelli jerseys as well. Definitely recommend ordering a size up.

Perfect
- Familiarity:
- I've put it through the wringer
- Fit:
- True to size
This base layer is, as the title says, perfect. I have an athletic build, and as such, I have a problem finding clothing. This fits great, just as it did when I had a slimmer, racers physic. In short, it adjusts well to body shape. It is soft, works very well as an insulator or as a wicking layer. It is very versatile and will most likely be adding a second as well as a sleeveless. It runs true to size as long as you following the Italian sizing which is usually one size small than US.
