I went to go try on some track suits today, and how tight is too tight? I tried on one, the fit looked alright but I could barely breathe and could not make my back straight. I tired on a different one and it felt great, but looked a little loose. All the track suits i tried on were a pain to get out of though. Im looking at the agv sport race suits, looks pretty good for the price. Im 5'10'' and 165 btw, is 44 a good size? thanx in advance.
