The Pumpin Pal Supershield is a breast pump flange designed for enhanced comfort and efficiency during pumping. The 'NEW' likely indicates an updated or improved version. These flanges are ergonomically shaped and made of soft, flexible material to conform to the breast, aiming to reduce nipple irritation and increase milk output. They typically come in various sizes to ensure a proper fit, which is crucial for optimal pumping. The design often includes a wider, angled opening to accommodate a broader range of nipple sizes and shapes, potentially improving milk flow and overall pumping experience.
