You need to be flexible to even get it on right
I ordered a large and it was hard to get this to work right without help. THe straps are not that long and so to grab them and tighten them is near impossible if you don't have flexibility.  I had to set one side and put it on lop sided to then be able to grab the strap to pull it tight. Once I did that I was able to wear it for a short time to test it out. I think this is basically  a waste but I wanted to try it. It preforms as I expected. This will be turned into something else so I can get some type of use out of it.
