This is my first uniform for iaido (superlight set). I am ~185lbs and just under 6'2", and the gi size 4 seems like a pretty good fit. The size 27 seemed to fit well, but an instructor told me it looks one or two sizes too small. I think a 28 would be best. This is because in iaido, the hakama is slightly longer than in kendo.
The quality of the gi is superb, and the look is nice. It's light, soft, and supple but feels solid. Surprisingly soft and light for something that feels like strong quality material. The hakama has stitched pleats and is standard tetron. It feels fluid when worn. The color of the gi is black, and the hakama I think is black too, but is a bit more blue than the gi. As I am new to the martial art, I don't have much to compare to so take my review with a grain of salt.
As for the ordering process in general, there was little communication. My account said the order was "pending", but when I sent an email to ask a question they mentioned the order was already shipped. I didn't receive any tracking code or notifications about it being shipped or delivered. It was shipped and delivered quickly, though, it arrived 3 days after placing the order.
Also, note that this product does not come with an obi. You will have to buy one from somewhere else if you need one.
I think new and veteran practitioners in kendo or iaido looking for an affordable uniform would probably do well with this set.
