Store, freeze, and monitor breastmilk with presterilized storage bags featuring a color-changing temperature indicator, leak-resistant double seals, and a space-saving design. The built-in temperature indicator changes color to help you quickly identify whether milk is cold, at an optimal feeding temperature, or too hot. Double side seams and a double zipper help protect every ounce from leaks, while the separate pour-in and pour-out design reduces contamination risk. Freeze bags flat or upright to maximize freezer space, and label each bag with the convenient write-on area. Take your health to the next level with HSA eligible Baby & Mom products.
