I injured my shoulder severely, so I had to buy this arm band in a hurry. I'm 5'5, have a bit of extra weight, but I'm not excessively overweight... the arm band doesn't have enough adjustability for larger sizes... I have it velcroed as far as it can go, and it's still too tight, which means I can't position it properly on my shoulder because it won't fit on my arm. On the other hand, the band that goes around my torso is tightened to the maximum without overlapping, and it's still a little loose... I can loosen it to fit someone twice my size... but I can't make the arm band any looser, and that's the crucial part........................... it's not helpful at all. It would be great if it fit properly. Unfortunately, I don't have the luxury to wait for another one to be delivered.
