Sick-Stick Replacement Flag 12" X 16". This flag utilizes a velcro sleeve used on whip models from 2017 to early 2021. Flag is dune legal in most areas. Please email or call us if you are looking for a particular flag size, design or color to match. Note; our early model whips used a 9"×12" , contact us if you need this size as our quantities are very limited for the smaller flags. All our flags are heavy duty & custom built to our specs - they are double sided, double stitched to last and use a heavy duty velcro sleeve.
