When I tell you that this thing compresses, It freaking COMPRESSES! If you need something that tucks everything in in all the right places and makes you sweat, this thing does the trick! I did notice that it was nearly impossible for me to zip it up when trying to get into it, but then realized that if I squeezed into it while it was zipped and only unzipped it when I was getting out of it, it held up nicely! It is a bit of a work out getting into it, but the fabric is pretty strong. So far, I am impressed considering I got such a good deal on it.
