Many are labeled One Size Fits Most or with general labels like Adult, Women’s, Men’s, or Kids. Common adjustment features include internal hook-and-loop (Velcro) size-adjustment bands, hidden size adjuster bands, snapback or adjustable straps, and elastic or length-adjustable chin straps on character masks.
Some hats add interactive and novelty details such as raised 3D eyeball props, soft sculpted eyes, vinyl eye pieces, bendable wire antennae, hidden pockets for cash or ID, and concealed spray bulbs with tubing (one listing notes a spray range up to 25 feet). Not every design includes these features—check the product description for specifics.
Common closures include back snap closures, internal hook-and-loop (Velcro) size-adjustment bands, adjustable straps or snapback closures on caps, and elastic length-adjustable chin straps on some character masks.
Product details for multiple listings indicate no batteries are used; several entries include the line “Battery: No Battery Used.” Verify the product description if you expect any electronic features.
