I bought this because I had to see how it compares to the much more expensive Shock Absorber that looks the same.  It looks almost the same put side by side, but the straps are not the same and the fabric isn't exactly the same.  It doesn't give the same support.  Either the sizes run big or the fabric stretched out too much because it is not the same fit at all.  Too bouncy for jumping and jogging for me.  Just had to make sure I was getting what I pay for!
