The original cap washer that washes your cap and still keeps its shape. Plastic shell allows you to wash your umpire or referee cap in the dishwasher (top rack) or washing machine, yet still maintain its shape. DO NOT USE DETERGENT! That is poison to hats. Wool hats must be dry cleaned. Remember that, if you sweat, a 100% wool hat will shrink a little. Design allows for accelerated drying. Also prevents crushing during travel or storage to and from games. Safe for wool or mesh caps. Made in the U.S.A.
Ball Cap Buddy is the only cap accessory of its kind. There are others out there that copy it, but this is the original.
