Helps stop the slouching posture
I was having some back pain and decided that bad posture was the likely culprit. I began to wear this a couple hours per day at work and noticed that it helped me stand taller again. My back pain has lessened using this along with doing some back exercises. I gave just 4 stars for comfort because the shoulder straps become uncomfortable in the under arm area after wearing for a while but Wearing another shirt underneath it has helped.
Rating: 4 stars
