When you were gripped by disco fever, you couldn’t have your pants falling down in the middle of the dance floor. Luckily, with your Ban-Roll waistband, your polyester digs were sure to stay firmly around your waist. The patented Ban-Roll waistband promised to “not roll, curl or crush”, and you can be sure John Travolta spent his Saturday nights boogieing down inside his high-waisted sansabelt slacks.
Polyester was the fashion keyword in the disco era, and sansabelt slacks were everywhere. However, belts and suspenders were not, and those pants needed to stay up somehow. The Ban-Roll waistband was a specially constructed piece of corrugated elastic that kept the pants snug against the body by gripping onto skin or other fabric. You could maintain that smooth polyester look from top to bottom without anything getting in the way.

 

Funk stars Sly and the Family Stone took the sansabelt look to the next level by pairing double knit polyester flaired pants with a high, three-button waistband. The texturized elastic worked as both a fitting device and a built-in suspender, and allowed easy, funkedelic movements on the stage.

 

Ban-Rolls have survived in the post-polyester world. They now hold up the pants of athletes and P.E. teachers everywhere. Belts and suspenders just wouldn’t cut it on the athletic field.
