Ahhh, that's better.

Designed with cooling airflow and quick-drying comfort in mind, the Castelli Men's Flusso Full-Zip Jersey is an ideal choice for training through the dog days of summer. It sports a semi-fitted design that follows your body closely, but isn't a skin-tight race fit. Castelli's Prosecco GT fabric is lightweight and actively wicks moisture away from your skin, helping your body regulate its core temperature when you're exerting yourself on those hot summer days. This lightweight polyester fabric is paired with breathable mesh panels along the sides, which channel cooling airflow across your body as you pick up speed.

  • Ultra-light, breathable jersey designed for hot weather
  • Semi-fitted design follows your body without being skintight
  • Prosecco GT fabric is both lightweight and quick-drying
  • Breathable mesh side panels provide cooling airflow
  • Three standard rear pockets for functional storage
  • High-visibility strips for being seen in low light

Great summer jersey

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: medium

Fit as expected, a bit close fitting but it's a light weight summer jersey. Certainly not skin tight. Good cut , but to skin tight. Worn it with a wicking base layer many times and it worked great unzipped on climbs.

Don't understand the "catering to obese" comment. At 60YO and 155 I have been a medium since my 20's, I just have a generic cycling body. This was well cut and as expected for the size.

Good Quality and Materials

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: Large

I really like the quality of this jersey. The material is quite comfortable and I haven't put it to a true test yet, but feels very lightweight and breathable. I found the design to be good with the sleeves a comfortable length. The fit will work better for some than others - it's a slim fit but not a second-skin race fit like some of Castelli's jerseys. As typical with Castelli I found the length a bit short - it works ok with bibs but I would have preferred another inch or so in back for my tall frame.

Poor fit, not typical Castelli

  • Familiarity: I returned this product before using it
  • Fit: Runs large
  • Size Bought: Large

Castelli is now catering to the growing percentage of the overweight and obese. Fit in the shoulder and upper chest area was OK but below that this jersey is an absolute tent. I'm a large in Castelli jerseys, I own 8 others and they all fit the same, which I can honestly describe as "perfect": comfortable but skin hugging, very aero. This one is out in left field. Maybe it's a manufacturing defect but I don't think so. After some searching I found a picture of the jersey on a model, sure enough there are noticeable wrinkles in the jersey around his mid section, and he wasn't rail thin. If Castelli is starting a "big mens" line of clothing I really think they should have labeled this as such.

At 5'10" and 150, Ken is a very skinny human and obviously he must think that anyone heavier than that is overweight? The Flusso is a slim fitting jersey, maybe not form fit yet it is by no means relaxed. I am 6'1", 180 and represent more of a standard and average (not overweight) body type and the Flusso has a very short trunk and skinny arms. I couldn't use it but I could see those with a shorter mid section and skinny cyclist arms liking this jersey.

Hummm, maybe I should be focusing on Castelli jerseys. But seriously, setting aside the fact your claim that a L fit your upper body, at your size I'd think a M would be more appropriate than a L.
