The Truweo Posture Corrector works to improve your slouching by offering shoulder support that develops muscle memory to keep you standing straight, even long after you've ditched the corrector. The unisex alignment device is made of a lightweight material that can be worn while you're sitting, standing or even working out. The material is completely washable, so don't worry about sweating while wearing it. It's also undetectable under clothes, so you can wear it out and about without feeling self-conscious about having the corrector on.
