-Made of leather and chromed steel -POW MIA design -Chrome chain **From a dog & cat friendly home** What are vest extenders used for? If you have gained a little weight and you cannot snap your vest closed, the use of these vest extenders allows you to keep your same vest but make it larger. Wearing vest extenders allows the wind / breeze to get inside your vest without your vest blowing wide open. Keeps you cooler on those long hot summertime rides. Because they look so darn cool! Great looking and many design choices to choose from in our Vest Extenders department. Thanks for looking 😊
