Cap-Ban-Nu™ Padded Cotton Knit Hat Size Reducer & Sweat Liner – Medium Fit Adjustment

Improve the fit and comfort of your hat with the Cap-Ban-Nu™ Padded Cotton Knit Hat Size Reducer & Sweat Liner, designed for medium fit adjustment (≈½ size) while absorbing sweat directly against the forehead. The added padding provides noticeable correction without stiffness, making it a versatile choice for a wide range of hats.

The soft padded cotton knit surface sits comfortably on top of the existing sweatband, helping protect hat interiors from moisture and makeup while improving fit throughout extended wear.
