CustomFit Flanges: 3 Sizes Included....Every mother needs her breast pump flange to "fit" for the greatest comfort and best milk flow. Enjoy a good flange fit at your very first pumping and later as your body changes. Purely Yours Ultra features three of the most commonly needed flange sizes and easily adapts with four others available separately.
To get an idea of your flange size, compare your nipple to a U.S. nickel. If your nipple is wider than the nickel, you will likely need a larger-than-standard size breast flange. But because the breast changes as you pump, measuring tools alone are not the most reliable gauge. The best way to find a good fit is to try different flange sizes until you find the one that feels best and give you the most milk.
