The Classic PD Security Band™ is excellent, if your body temperature tends to run a bit cool.  If you like extra support, it is great.  While the Classic offers a strong sense of support, it will not constrict like a back brace or a girdle.

Fabric Contents: 88% Polyester and 12% Spandex.

Care: Machine washable in warm water.  Lay flat to dry. 
Do not use excessive heat or bleach.
