Designed for busy parents who pump on the go, this eight-piece silicone set helps you tailor the shield opening to your own nipple and pump style. It works with a wide range of 24mm wearable pumps, offering flexible options without forcing a change in your routine. The soft silicone texture provides a gentle touch against the skin, supporting a comfortable pumping experience across different brands.
Whether you use Momcozy Air1, W1, M9, M6, M5, or S12 Pro, or you reach for Spectra, Medela, eufy, Lansinoh, Elvie, MOMMED, Nuliie, and more, these inserts can help align the shield with your unique shape. By reducing the nipple tunnel to a more suitable size, the fit can feel snug without excess pressure, potentially improving how smoothly milk is expressed.
Because this set covers a wide spectrum of brands, you can fine-tune fit across devices without buying separate pieces for each pump. This versatility makes it easier to adapt as needs change, whether at home, at work, or while traveling.
The kit includes ten size options ranging from 13 to 22 mm, designed to accommodate shifts in comfort and pumping goals. A precise nipple sizing tool is included to help identify the best match for different stages, making it easier to find a comfortable, consistent fit.
For easy care, the inserts are simple to sterilize via steam, boiling water, or microwave steam bags. After use, wash with mild soap and rinse well. To maintain optimal performance, consider replacing every two months.
Note: This accessory is designed to complement your existing pump system. While it can offer a customizable fit and potential comfort improvements, results may vary by individual setup and routine.
