Say goodbye to the 1950's breastmilk storage options! Clunky coolers, bulky bags, batteries and cords are SO yesterday. Ceres Chill keeps breastmilk or formula safe for up to 16-20 hours with just a handful of ice!

And now you can enjoy the convenience of one full-sized 27 ounce Breastmilk Chiller and one 12 ounce Demigoddess Mini Chiller! Having two Chillers frees you up - never worry about those extra few ounces at the end of the day that don't fit in your OG Chiller. Never stress about having an epic, compact way to store a few ounces of milk while you're out of the house. We got you! 

Pump directly into either chiller and enjoy up to 20 hours of safe chilling. Compatible with all major breast pumps, and you can even use the lid for double-pumping or feeding your baby with a standard nipple assembly!

  • Store the nipple safely and cleanly in the upper cup.
  • When you're ready to feed your baby the chilled milk, remove the nipple from the cup and connector.

Bulkier than I thought it would be. It good for the most part but depending on the use and weather, sometimes it doesn't stay as cold as you'd like milk to be and/or it condensates water into the milk. Overall nice quality and better than other options!

Love it!

Love it. As a nurse it’s so easy and convenient. I work 12 hour shifts and it stays cold all day! I do wish there was one that held more than 27oz. As someone who produces well over that I need more room. However, that is why I bought the duo. I just hate carrying 2 chillers for work. I already have 3 bags I have to carry to work.

Alexis G.
Definitely Duo!

I absolutely love my OG Chiller/ Demigoddess duo purchase. I’ve been using my Chiller in replacement of a lunch bag cooler and ice packs to pump and store my milk throughout my workday and it’s worked out awesome. I use the duo for travel, chiller keeps the milk nice and chilled and the demigoddess I use to warm a bottle up when we are on the go. No more traveling with my plug-in bottle warmer. I’ll be traveling to a destination wedding later this summer and I’m no longer stressing about keeping my baby’s milk cold enough for the flight or where/how I’m going to warm a bottle for her when she’s ready to eat. Thank you!


These are literally amazing, any pumping or breastfeeding mom I totally recommend these

Overall a great product!!

I have mostly been using my mini chiller (the Demigoddess)—it works very well to transport enough pumped breastmilk for an outing or if I’m leaving my baby with my family for a few hours! I anticipate using the larger chiller for when I return to work and am gone for longer. One downside is that when you pump into the chiller directly, they are a little heavy and so pull down a bit on the pumping flange if up and about—it’s an excuse to plop in front of a book or TV while pumping!
