Cap-Ban-Nu™ Terry Cloth Hat Size Reducer & Sweat Liner – Maximum Fit Adjustment

Improve the fit of your hat with the Cap-Ban-Nu™ Terry Cloth Hat Size Reducer & Sweat Liner, designed for maximum fit adjustment (up to ≈1 full size). This thick terry cloth liner is the most substantial option in the Cap-Ban-Nu™ line, making it ideal for hats that are noticeably too large and need significant size reduction.

In addition to reducing hat size, the terry cloth surface also absorbs sweat where it rests against the forehead, helping protect hat interiors during extended wear.

Which hat size reducer do I need?

• Thin Cotton Knit – Light adjustment (~¼ size)
• Padded Cotton Knit – Medium adjustment (~½ size)
• Terry Cloth – Maximum adjustment (up to 1 size)

Key Benefits

• Maximum fit adjustment (≈1 size): Best for hats that are clearly too large
• Thick terry cloth construction: Provides the greatest amount of size reduction
• Comfortable against the forehead: Soft terry cloth surface
• Added sweat absorption: Helps protect sweatbands and hat interiors
• Easy application: Peel and stick directly on top of the existing sweatband

How It Works

Peel and stick the liner directly on top of the existing sweatband, where it rests comfortably against your forehead. The thickness of the terry cloth provides maximum size reduction, with sweat absorption as a secondary benefit during wear.

For lighter or moderate adjustment, see our thin cotton knit or padded cotton knit versions.
