The purpose of this CHAMPION shoulder brace is to remind the wearer to maintain a correct, healthy posture.  Padded shoulder straps pass under the arms snugly and criss-cross in back.  When the shoulders slump, the straps become tight around the underarms and remind the wearer to resume proper posture.  Allows for normal movement without binding.  Degree of support is adjustable by tightening the shoulder straps.  Easy to apply and remove. It is also a constant reminder to sit, walk, and stand with proper posture. Fits Men and Women.
