Keep freshly pumped breast milk chilled throughout your day with this reusable breast milk cooler featuring a pre-freezable water-filled cooling core and 1.7-quart/1.6L vacuum-insulated 304 stainless steel flask. Pre-freeze the cooling core for at least 12 hours before use. In a 28°C/82°F ambient test, internal temperatures reached 5°C/41°F at 4 hours, 2°C/36°F at 8 hours, and 4°C/39°F at 15 hours. The reusable HDPE core uses pure water instead of chemical gel and eliminates the need for loose ice cubes. Airtight, leakproof seals on the inner bottles and outer flask, plus a built-in handle, make the cooler convenient for work, travel, daycare drop-offs, and daily commuting.
The set includes two 11 oz/325 ml wide-mouth bottles with visible volume markings for 22 oz of total storage, allowing freshly pumped and previously chilled milk to remain separate. The bottles are compatible with Momcozy wide-mouth pump fittings and matching baby bottle nipples for convenient pump, store, and feed use with fewer transfers. An ergonomic raised grip makes the flask easier to open, while BPA-free, dishwasher-safe components simplify cleaning. After breastfeeding, the stainless steel flask can also be used as a hot or cold beverage thermos and accommodates beverage containers with an outer diameter under 2.6 inches/6.7 cm. Package includes 1 breast milk cooler bottle, 2 inner bottles, 1 cooling tube, and 1 user guide, backed by a 3-year warranty.
