The concept is smart, but execution is weirdly lacking.
First of all, the hoops are too short! for a big man, with winter coat on, it's very hard to even get your arm through the second hoop when putting it on.
Second; the bottom attachments of the hoops are too close together, making the hoops dig into the sides of your back, super uncomfortable.
Also, the hoops are really narrow and almost not padded, feels cheap, and not very comfortable.
Would not buy this product again.
