Baseball Cap Washer Frame - 3 Pack Hat Cleaning Cage Protector for Washing Machine | Gentle Wash for Baseball Caps, Snapbacks & Hats | Perfect for Laundry, Travel & Sports Gear Care

The brim of my hats were curved, so the frame didn't close completely. I was able to get it to snap and fit the cap part perfectly. I used this in my dishwasher. the hats came out clean and dried perfectly. I would definitely buy this again.
