This is an Italian-made suit, so I ordered both the L and XL, thinking that I would keep the one that fits best and return the other. I'm 6'1 tall and I weigh 180 lbs, and I could _barely_ squeeze into the XL. The legs fit fine, but the top part of the suit is so constrictive that it took me a few minutes to figure out how in the world I was going to get it on! I had to _squeeze_ one arm through, pull up on the upper back of the suit, and then somehow _squeeze_ the other arm through. I was honestly terrified I was going to rip it somehow. Once it was on, it had a very snug (even skin-tight) aero fit. The black matte with shiny black detail inlays looks awesome. The design and quality of the suit was very good; you're going to look great wearing it.
I think this suit was designed with diminutive European cyclists in mind, and I have a more muscular upper body than the typical cyclist because of weight training, so maybe a 2XL (or even a 3XL?!) in this brand would work better for me. On the other hand, I have a Castelli Sanremo suit in size XL that is my go-to road kit and it's slightly too large, so go figure. The main difference between this suit and the Castelli (also an Italian brand) is how the zipper is designed. The jersey portion of the Castelli can be unzipped and completely separated, giving a lot of flexibility when getting into or out of the suit (which comes in handy for bathroom breaks!). The zipper on the Nalini cannot be separated, and the suit is still quite restrictive even when the zipper is all the way at the bottom. I'm sure there are aero, weight, and durability benefits to the Nalini design, but it makes for a less easy to use suit.
I bought this because I love my Castelli Sanremo suit, and I wanted something with a more European style. However, this is really designed for a timetrial, when every second or fraction of a second counts. It wouldn't be good for every day riding. It is too difficult to get on and off, and it's not good for bathroom breaks. Unfortunately I will be returning this suit. FWIW, the chamois seemed to be high quality, like everything else about this suit, but I never got any saddle time with this suit, so that's all I can say.
