Castelli Free AR 4.1 FZ Short Sleeve Cycling Jersey - SS18
This jersey is an evolution of Castelli's top pro racing jersey from just a few year back. It’s also the first aero race jersey that didn’t get retired when the next generation of faster, more aero jerseys came along. 
 
For the 4.1 version has taken a different direction compared to the older 4.0 jersey. This updated jersey gets a zippered rear pocket, a flap behind the zipper to protect your neck, updated Velocity dimpled fabric on the front and an angled pocket for easier access. This makes it the one ideal jersey for all your rides, whether you’re sprinting for the win or trying to survive the Sunday group ride.

Very happy with this product. Great fit from the jersey witch is made with premium materials.
Nice race style jersey. Tight fit cut. Very thin fabric which makes it slightly transparent. The label inside should be made of softer material. I've cut it. I am 177 cm and 74kg and size L is just fine. As always Castelli runs small.
This is a very comfortable lightweight jersey, open pockets on the back are great for storing a waterproof and food gels etc, the zip pocket is ok for a medium size phone. Fit size is best if you go up a size.
Castelli jerseys are always on the small side, common knowledge, this jersey is no exception. I'm 190cm/95kg and 3XL fits like it's been sprayed on, I wanted a firm fit and that's what I got
Great and comfortable summer riding top. As always, tight Castelli fit. XL fits me with 1,79m/82kg.
Great fit, great quality at an attractive price. Very pleased
I'm 1.7m 59kg (5'7" 130lbs) and they are a snug fit. They'll be a perfect after a few rides when they stretch a bit. Quality, light weight material perfect for hot summer days.
Good fitting, light and breathable materials
Perfect jersey for summer days, nice and light and very breathable. The arm length is not as long as the aero type jerseys, but they still have the raw edge which is nice. The length is just right and the gripper is pretty good too, there is also a useful zip pocket, which you don't often get anymore. As with all Castelli jerseys, it comes up pretty small, so size up accordingly.
Good fit. A little tighter in the collar section compared to previous releases of Free AR.
This is a great summertime jersey for fast group rides. Wicks away moisture very well and I like the tight fit.
The jersey seems to be well made and fits me well. I like the cut of the jersey (flexible, but form fitting). I have only used it twice so far so I can't report on durability. I would give it 5 stars except I find it crazy that even within the Castelli line, sizes are inconsistent. Even if you figure out your size for one Castelli jersey, a different Castelli Jersey could require a different size. It makes buying online stressful.
