Ceres Chill is the world's first breastmilk storage system. With our patent-pending double-walled, dual-chambered, stainless-steel system, moms can pump all their milk directly into a Ceres Chill thermos while working or traveling. Ceres Chill makes breastfeeding and pumping much, much easier and much more stylish. Safely store your milk as you hit the gym or head out on a date after a long work day. When you're done breastfeeding, use it to chill and not dilute iced coffee, wine, beer, or sports drinks—turn your Ceres Chill into your greatest ice cold, fruit-infused water bottle or enjoy coffee and perfectly steeped hot tea for hours. * Compact, stylish, and dishwasher-safe * 20+ hours of chilling storage for 12 oz — Need more time? Just add ice! * Airport friendly * BPA/BPS and DHP free * Becomes a beautiful coffee thermos and water bottle to use for years after you're done breastfeeding.
