No other gi on the planet shrinks more than this. I wear an A3, and the A3 Gameness Air shrank into an A2. I bought the A4 to replace it, and it shrunk to a cozy A3. I have seen gis shrink, but usually a shrunk A3 is a snug fit, this shrunk A4 is snug.
As far as comfort, you can't beat this gi. It breathes well and honestly I don't even feel it at all. The collars are easy to grab and hold onto, so I find myself getting into some trouble there, but as mentioned in other threads, it helps you work on defense a bit.
The pants are an odd cut. The waist is big, but snug when drawn in with the strings (nice, thick and soft strings that I like very much, and the loops seem sturdy enough). However, the thighs seem cut wider than need be. The length is fine.
The skirt length is a BIT long for my tastes, as I seem to get my partners feet tangled in it more than my other gis. Still, this is not a complaint, just something to consider.
If anyone has any specific questions, i'd be happy to answer them. Just be sure to buy a full size over what you usually get for this one.
