I've been trying different support undershirts. My work has me bent over for hours a day, and I've been doing that for many years. I've become somewhat rounded over in the thoracic spine, and round shouldered. As a result, I have developed pain - especially when I work. This undershirt does virtually eliminate the pain, but is very tight - to the point that I feel like I have to take deep breaths in occasionally to get more air. Perhaps I will get used to it - or it will stretch some, but to early to tell. Also, I ordered a size larger than measuring suggested. One more thing, I wear this over a cotton T shirt because the material is not something that I would like next to my skin.
Fits and Works Well, but is Short

The shirt seems to work okay, aside from never staying tucked in. Otherwise it fits perfectly. I'm probably taller than a size small was intended for.

I have been wearing and washing this shirt every day now for a week and not only is my posture better, but I have also noticed less neck pain. I am ordering another one, so I do not have to wash so often.
Great for Posture
5
Absolutely great for posture. Need to wash it several times to make it more comfortable, but I can wear it all day for excellent posture without overly compressing or stressing chest and shoulders. Worth trying.

Underworks Posture Control and Training Shirt Top Gynecomastia Chest Binder 420

Powerful posture corrector brace

Underworks Posture Control and Training Compression Tank Top

The Men’s Posture Corrector Shirt is perfect if you find yourself slouching from the office grind, have a weaker back due to injury or instability, or just want a more powerful, confident posture.

Made in USA.

Underworks Posture Control and Training Shirt Top Gynecomastia Chest Binder 420
Better Posture, Better Health

Underworks Men Posture Corrector Shirt, Firm Compression

  • Engineered to support the upper torso muscles your body uses to maintain good posture.
  • Resistance bands cross your shoulders and down your sides, while midriff compression mimics an engaged abdominal area to counteract the upper bands.
  • Tummy Flattening Benefits.
  • Specially contoured back helps avoid lower back slouching and stooping.
  • Outer shell is a nylon-spandex tank for discrete use under clothing.
Supports posture and Midriff Compression
  • Supports posture by integrating strong resistance bands in an “X” formation across the shoulders and down the sides—this design gently pulls the shoulders back and aligns the upper torso.
  • Bad posture can really be a pain in your back but, with a posture corrector brace, your upper body has the additional support it needs for better alignment.
  • Midriff compression helps engage your core to support posture alignment and maintain an upright stance.
  • Our Men’s Posture Corrector Shirt is designed to offer support to the muscle groups that are instrumental to better back health.
  • Contoured lower‑back panel combats slouching or stooping that often begins in the lumbar area.
  • In many cases, rather than using our muscles to support themselves, people rely on the spine, which was not intended to support your head and upper body over long periods without muscular support.
  • This men’s posture corrector shirt mimics those tight, compressed support muscles, resulting in a healthier posture for less pain.
