Solid back support, easy to adjust
This posture corrector is well made and genuinely helps with back alignment. The straps are adjustable and comfortable to wear for extended periods. I notice a real difference in how I carry myself after wearing it consistently. Good quality for the price.

Fantastic Support, No Breathability
In my opinion, the most important things you need to know about this brace are: + I've bought it twice (lost one in a move) because it's just that good. I shop around for everything, but not this. This brace works. It offers full back support and does a great job of sort of redistributing your body's weight by looping around your shoulders and having the attachment points for those shoulder straps be your waist. + I used this for long periods and very regularly; the velcro never stopped working, even requiring much less frequent cleaning (in a 4-pet home no less) than what I've grown used to with other velcro things. + The metal bars that rest against your back go all the way from the base of your neck to your hips; they don't prohibit movement unnecessarily, do a great job of stopping you from moving in harmful ways, and do not ever bend out of shape! + The material is stretchy, doesn't look bulky or awful, and the belt area now has little gripping strips so that it doesn't ride up! - My only real complaint is about the supposed "breathability;" it has NONE. Good for them for thinking to have this be made from mesh for the most part. The problem with this? It's only mesh on the BACK! As in the outside, the part that doesn't touch your skin! It doesn't need to be breathable there! It's all open! The part that rests against your back? It's a stifling solid material, the same that's used to make the velcro stick. They just continued that velcro material onto the part that presses against your back. This brace would be a hundred times better if the mesh was against your back and not just for show on the outside.

Life-Changer for Posture Improvement!
Effective Posture Improvement: This posture corrector works wonders. It firmly pulls my shoulders back where they belong, effectively relieving the discomfort I used to experience. It has significantly helped me with my slouching and humpback issues. Impressive Back Support: The double cross design and the support plates in the back strip provide outstanding support from all angles. This helps to gently disperse tension, promoting alignment and stability without causing any harm to my back. Ultimate Comfort: This posture corrector is made with a breathable and comfortable material. The wide straps diffuse pressure points and don't dig into my underarms. The added underarm soft pads are a great touch, and I can easily adjust them to my most comfortable position to reduce any friction. It's comfortable, effective, and easy to use. If you're struggling with posture issues like I was, I highly recommend giving this product a try.

Helpful for Posture, Just Not Ideal for Long Wear
I really like the idea of this posture vest — it definitely helps me stay more aware of my posture, especially while sitting at my desk or doing light tasks. It provides decent support and is easy to put on and adjust. That said, it can get a bit uncomfortable if worn for longer periods, as the straps start to dig in a little. I think it’s great for short daily use, and it’s made well overall. With a few comfort improvements, this could easily be a 5-star product!

Saved my life !
I've been experiencing a tremendous amount of back pain, I do alot lifting, bending, stretching, alot of repeative movement that involves my upper back, shoulders, and arms. Before this product, I couldn't sleep, had a difficult time taking a shower or changing my clothes, I couldn't sleep because it's the pain was so uncomfortable. I bought this because traditional methods were not working!! I went to the doctors and I was prescribed muscle relaxers (4 times a day 🤦🤦) and take over the counter pain medication, and continue other home remedy treatments to ease the pain, using icy-hot, taped up my back to take pressure away, hot showers and stretching afterwards. AFTER I bought this brace, absolutely NO BACK PAIN SINCE, I wear it every time I work and afterwards I take it off and relax, and I haven't had any pain since I wear this consistently and continue other methods. But thank you, I couldn't find nothing in stores and this honestly helps me for my everyday life, I have my coworkers asking about it and i tell them like I'm trying to promote/sell it lol I can confidently say, I highly recommend it.

Que paso porque está más pequeño?
No decepción total he comprado siempre este corrector, soy talla L y lo volví a pedir pensé que era un error que me llegó talla S pero volvió y llegó pero está demasiado pequeño lo compare con el anterior y la tiras no son largas son muy cortas no se que paso, pero está vez no me gustó. Ya intenté ponerme lo y me irritó los brazos.

Most comfortable brace that I have found yet.
This is a very sturdy, very comfortable shoulder brace. I have tried many others that were either flimsy and didn't support or that were just absolutely uncomfortable. My only complaint is the back meshing bunches up and I have to continually pull it down if I want to wear a shirt over it (see photo) And also, the boning is not secured in there so it can be removed if you'd like, but one side of mine slips down every so often and I have to push it back in. But all in all, I'm extremely happy with this product and recommend it. Very comfortable and well made.

This will not help you
The design is poor. No matter how tight you get the waist, it will ride up and the tension on the shoulder straps will slacken. Not to mention that bracing your back will just make it atrophy. Maybe this could be useful for a hunchback, but if you have normal posture issues, I don't think you'll get anything out of it. Try yoga instead, it will change your life.
