I've had the sweet sweat waist belt for some time and wanted to get a new one as it's currently old and stretched out so I thought this time around I would try out one of the upper body suits but SS doesn't sell them that way only the belt which led me to trying this suit out.  I used it for my gym workout like usual and I did not get one drop of sweat under this suit.  As old as my SS waist belt is, it is is always dripping with sweat when I come from gym and take it off.  This suit did not have the same effect and I did quite an intense workout.  Also, the fit was okay there was a piece under the zipper that came poking me but it wasn't anything huge and I would have figured out something to alleviate it if this suit worked as well as I had hoped it would unfortunately it did not and is going back and I'm ordering me a new SS belt instead.
