It has potential!
I bought a men’s extra large regular strength. For my chest size, I should have been able to get a bigger one. So this one is kind of tight. A way to improve it I think would be to put the foam rubber over the full length of the rubber bands so that you have comfort all through your shoulder area and under your arms. Because this one is so tight I do have concerns about it restricting bloodflow into my arms because I did notice that the inside of my elbow joint seem to create pockets that perhaps could’ve been lymph nodes or just muscles then bulged a bit more due to the restriction of the bands. It might be a health risk. Not really sure.
