If you fish as much as we do, chances are that somewhere in your vehicle there's a collection of flies impaled (some permanently) in your upholstery. While this decorated interior works for some, a wiser alternative would be to get a Cliff Head Liner Fly Patch! Designed to clip securely over almost any car or truck's sun visor, this removable patch features Cliff's durable pre-slit blue foam to securely holds flies of all types and sizes. Visor Patch measure approximately 6.00 x 3.75 inches.
