Breast Milk Cooler

A breast milk cooler bag wraps double layer insulation around upright bottle slots, sized for a working day of pumping rather than a picnic. It rides the commute and the daycare handoff, and the backpack version carries the pump and its parts in the same trip as the milk. The CDC's storage guidance allows expressed milk up to twenty four hours in an insulated cooler bag with frozen ice packs, and that window is exactly what these are built to use, so pack the ice packs frozen solid and the whole day is covered.
