Castelli Climber's 3.0 SL2 Cycling jersey (XXL, blue) - The aerodynamic road jersey for hot temperatures and steep climbsThe Climber's 3.0 SL2 from Castelli is a road cycling jersey specifically designed for hot temperatures and high intensity rides! The Flusso 3D fabric used on the front and sleeves is interspersed with mesh fabric to ensure sufficient ventilation. On the other hand, the StradaPro 3D fabric on the back focuses on breathability and moisture management, and is also extremely quick-drying. In addition, according, to the manufacturer, the back material is supposed to block harmful UV radiation. Material selection and their placement, as well as the seams, are based on CFD analyses. As a result, the jersey is fantastically aerodynamic despite all of its features that deal with heat and solar radiation. With that in mind, it makes sense that the pattern of this jersey also follows that of the Aero Race Jersey.The weight of the Climber's 3.0 SL2 is almost completely negligible - just 106g in size M! This extremely low weight makes the shirt ideal for mountain goats who can’t find climbs steep enough. Last but not least, the jersey fits like a glove, while the open cuffs ensure that no seams leave you chafed or get in your way.

This jersey fits nice and snug with great breathability. When the temperature and humidity are both high, this is my go to jersey. Love the orange color! I am 5'10", 165lbs and the medium fits perfect. Highly recommend.

I ordered this jersey which was pictured as mainly white with subtle gray graphic stripes. It came as mainly gray with very slight white accents. I wanted a white jersey for hot summer days, and ended up with a gray one.Just a warning for anyone else.Otherwise the jersey is fine. I am 5’10” and 155 lbs, and size L fits me fairly tight.
This jersey was heavily reduced, so I decided to buy it. It has the usual Castelli quality about it - good zips, stitching, pockets etc. The size is very snug and think you would call it race fit now a days. It's also has very thin fabric, so really only for hot days in the saddle. i have yet to wear it, but I'm totally confident it will be spot on - as I always find with Castelli.
I have three of these jerseys, they’re perfect for hot humid weather.Typical Castelli cut and quality, very form fitting race cut, super-light and breathable technical fabrics. Despite the exceedingly light fabric I’ve found Castelli to be very durable, I’ve never had a Castelli jersey develop any rips or tears, they wear very well season after season.I’m a medium in most other brand jerseys, but I always order a size up for Castelli. Unless you’re a skinny Italian pro rider with 2% body fat, order up a size.
I'm a big guy (6'4" 230) so I ordered a XXL but just laughed when it arrived and I held it up. I had just been folding my 10-year-olds shirts and it looked no bigger than those. Some stretch to the fabric of course, but I think I'd need at least an XXXXL in whatever Italian greyhound sizing Castelli uses. Back it went and didn't even consider exchanging for a XXXL, which is the largest they offer.
Purchased a Large in silver gray, and I literally laughed out loud when I held it up. It looked like it might fit a small child, it had to be a mistake in the label. For reference, I wear tight cycling clothes, I’ve been riding for 30+ years and formerly racedI’m 5’7 and 135 pounds, in street t shirts a size Small. In Craft I comfortably wear either Small (form fit) or Medium (regular clothes fit). Weird.
This is a great summer weight jersey, very well ventilated, and it's a nice slim race fit - check carefully on the size, as you may need to size up at least one size, it's snug fitting, but very comfortable when you get the size right!
Runs extremely small, the Large looked like it could fit my toddler. Had to return and upsize.
