I bought an Ouano lightweight gi, but it's too big and I won't be able to wear it. I didn't roll it in, so I can't review it from that aspect, but I did want to post up my experience with the sizing since it might help somebody (as sizing is a big issue for many people when buying a gi they can't first try on).
I'm about 6'2, 190lbs, with a 34 waist 34 inseam, and a pretty athletic build. Going by the Ouano size chart I bought the A4 which is for 6'1-6'4, 215-235. I went with this because even though I'm way off the weight category, I fit into the height category, and I get tired of A3 pants that shrink up to be high waters and sleeves that are too short. I figured sinch up the pants and I should be good with length. Anyway, when I got it out of the box I knew that it was way too big, but I figured if I washed it in warm water and put it in the dryer that I could shrink it up, so I tried that (which then cost me not being able to return it!). My other two gi's are A3, and they shrunk up to the point where I don't like them, so I figured I'd shrink up this A4 and it would be perfect.
This thing BARELY shrunk if it did so at all! No more than an inch on the sleeves of the jacket and the inseam. I mean, this thing took a warm water cycle and a full high heat dry cycle. Still damn near as big as it was when I bought it.
I don't know about a lot of company sizing charts, but I would definitely say Ouano is pretty on par. The A3 tops out at 6'1 215lbs probably would've been just fine based off the size of this A4 that is just too big to even wear. People would grab the wrists and control me like crazy.
Hopefully this helps any big guys out who are considering Ouano. And if you think the A4 is the way to go, PM me and I'll give you a sweet deal on mine!
