I have a long 3rd generation one. I am a 42 or something, and got an XXL. I originally got the XL but had to send it back because it was too small to even get on. When I finally got the new one, I found that I am too big to be able to close the velcro myself. It's impossible for me to reach my arm over my chest and under my other arm to close the binder (the velcro is down the left side of the binder). When I got it on, it wasn't very effective. It mostly just stretched around the topography of my chest like a bathing suit. The fabric itself feels nice, but it's in no way suitable for a heavy duty garment like a binder. It sucks especially because I was originally going to get another model instead to replace the one I sent back, but they recommended I stick with the 3rd generation. I wish I had insisted on the one I was going to get. So I basically have a binder that does nothing. Sending it back is too much money for shipping too. I don't know who it might work for, but it certainly is not a model I would recommend to larger guys. It's almost impossible to get on for me without help, and it doesn't do a very good job. That's my personal experience, so other people might have had more satisfactory results than me.
