Familiarity: I returned this product before using it
I was captivated by the look of this jacket and just had to give it a try. Unfortunately, it's much less generous than the size chart would lead you to believe.
I'm admittedly a big guy at 6'-3" and 275 lbs, but the XXL looked really close with a suggested chest size of 48-50", waist 41-43", and hips 47-49". My measurements are 49", 44", and 47" respectively, so only the waist size is pushing it. However, the jacket isn't anywhere in the ballpark. For one thing, I had trouble even getting my hands through the wrist cuffs. I don't have big arms/hands either, with a wrist circumference of 7 1/2". Once the sleeves were pulled all the way on they were basically skintight from the elbow down. I've never seen anything like that before. Beyond that, with the jacket hanging unzipped, It really needed another 6" or so to properly close and zip up without making me look like I was squeezed into a sausage casing. I did manage to do it somehow, but it was not comfortable. This was all with just a base layer on, so even wearing a simple jersey, let alone any insulating layers, would make it that much tighter.
Beyond that, the cut of this jacket is meant for a low, even aero position, as the description says. There's enough coverage in the back, but if you're standing then it tends to ride up in front like you'd expect. Had it fit properly, I'm confident these traits would prevent it from flapping in the wind or being excessively baggy in front which many jackets tend to be. The wrist cuffs act almost like a gasket, helping to keep them in place and stop air infiltration, and the sleeve length is nice and generous. The flaps in back will help vent moisture and prevent sweating The material is a bit thicker than you might think, though it's still light. It definitely falls between a light wind shell and a rain jacket. I'm not sure it would pack into a rear pocket as well as some others, but for cold and potentially drizzly days this would be a winner. I do have some concerns about long-term durability of fabrics like this. The material has the look of a plastic coating over a stretchy mesh matrix. I've had other jackets in the past with similar fabrics that broke down after several years, leaving just the mesh and losing all wind-blocking ability. I hope that's not the case here.
While I can't test it on the road, the quality, design, and fit/finish seem top notch. The oddball sizing makes me cautious though. This would not be a good fit for someone with strong biceps or much of any upper-body bulk. If you're a svelte racer with no body fat then I bet you'd like this one for however long it lasts.
