The 34oz cooler holds approximately a day’s supply of breast milk, while the 72 oz cooler holds more than a two day supply, for most moms.
The Pump & Ship options provide at least 72 hours of refrigeration from activation. The Pump & Tote options provide up to 60 hours of refrigeration from activation.
How It Works:
Milk Stork coolers rely on the principle of evaporative cooling, continuously evaporating small quantities of water at low pressure over hours and days of operation. Water flow within the cooler is regulated – responding to ambient temperatures – which protects the cooler’s contents from external temperature fluctuations during shipping.
