I don't recommend the Stormtrooperunderstuit version. I have one. It's cotton and it is UNBEARABLE in the heat. If you're going to use it for colder climates it might be okay. Also, once you start sweating in it, it gets SOAKED. Needless to say, I don't use it anymore. I have a Skin diving suit I bought that's a one piece, but have recently been using the 2 piece Eastbay under armor.
