This style actually works
Reviewed in the United States on October 26, 2019
TL;DR If you've been down this road already with limited to no success, get this style (that includes a belt), you will actually wear it and it will help. I put it on the first time and my 9 year old came in the room a minute later and exclaimed I had grown taller somehow.
I was an almost freakishly precociously tall kid with undiagnosed Asperger's who grew up in the 1980s, thusly I've suffered chronic cyclical severe myofacial pain since I was about 10. It turns out that trying to make yourself invisible causes considerable physical pain over time. Partially due to my friend aspergerbrain, it took until I was about 41 to seriously consider my posture as a culprit (coincidentally at the same time as diagnosis, imagine). Don't get me wrong, I've half-assed it my entire life: punishment, er, encouragement from parents, peers, employers; other posture trainers, tens units, chiropractors, acupuncture, acupressure, physical therapy, uncounted tools/massagers/exercises etc. A lot of the problem is its hard to get a consistent excellent posture for long enough to relieve long-standing pain. That leads to giving up or writing off posture as the issue when the pain never abates. Anyhow, lately I've been more open to my own errors and I tried a similar posture trainer without the belt and its just impossible. They constantly need readjustment and they don't have a strong enough pull to defeat the instinct of 40 years of intentional and unintentional kyphosis. I decided I would try them all until I found one; hiding away is for the birds. This one works! The belt lets you adjust the pull as hard as you need to and it keeps the straps in place almost perfectly. My shirt doesn't look at wadded up all the time either AND my freaking neck/shoulder area has had some relief! After several days use it has helped enough with pain relief that I feel excited looking forward. For your sizing information, I am 5'9", 122lbs, very fit, zero curves, medium frame. I bought the "medium" and it fits great, but I most definitely would have called this a size "small", at least in usa. Good luck fellow slouchers, they'll never see us coming! =)
