Learn how to set up, pack, and use the Latched x Ceres Chill OG+ for portable breast milk storage while pumping away from home.

Quick answer

Use the Latched x Ceres Chill OG+ as a portable breast milk cooler by pre-chilling the inner chamber, pumping directly into the removable container, and keeping milk cold with ice in the outer chamber.

Why the Latched x Ceres Chill OG+ works for on-the-go pumping

The OG+ design uses a two-chamber system: an inner chamber that holds your milk and an outer chamber that you fill with ice. This keeps your expressed milk cold without needing a bulky cooler or freezer packs. The Latched collaboration adds a motivational design, but the core cooling method stays the same.

Because the inner container is removable, you can pump directly into it using most standard breast pump flanges. Once you're done, you simply reinsert it into the pre-chilled outer chamber. This makes it practical for travel, work, or errands.

Step-by-step setup for pumping on the go

Pre-chill the inner chamber: Place the empty inner container in the refrigerator or freezer for at least 30 minutes before you plan to pump. This helps the container stay cold longer once you add milk. Don't skip this step — a room-temperature container will warm your milk faster.
Fill the outer chamber with ice: Add ice cubes or crushed ice to the outer chamber, then screw the pre-chilled inner container back into place. The ice surrounds the inner chamber and keeps your milk cold. Use enough ice to fill the outer chamber — partially filled ice reduces cooling time.
Pump directly into the inner container: Attach your pump flange to the inner container's opening. Pump as usual. The container holds up to 20 oz of milk, enough for most sessions. Check that the flange fits snugly — a loose connection can spill milk.
Seal and store the container after pumping: Remove the flange, place the lid on the inner container, and reinsert it into the outer chamber. The ice will keep your milk cold for up to 20 hours. Make sure the lid is tight to prevent leaks during transport.
Clean everything after use: Disassemble the inner container and lid, then wash with warm soapy water or place on the top rack of the dishwasher. The outer chamber can be wiped clean. Avoid using abrasive scrubbers on the inner container to prevent scratches that can harbor bacteria.
