This is the shirt that encourages proper posture to help prevent neck, back, and shoulder pain. Designed by the team physician for the Boston Celtics, the shirt has built-in filaments that conforms to your body's contours when your spine is aligned properly.

Whenever you slouch, an electronic sensor detects the increased tension in the microfilaments and vibrates to let you know your posture is not optimal (vibration ceases when you correct yourself).
