CERES CHILL OG Breastmilk Chiller, Reusable Storage Container, Up to 34 oz. - Bottle Cooler Keeps Milk at Safe Temperatures for Up to 20 Hours, Connects w/Most Pumps (White)

As an exclusively pumping mom, one of my biggest challenges has been keeping my milk safely stored when I’m not at home — and honestly, I didn’t realize just how essential a breast milk cooler storage system would become in my daily routine until I got one. Now, I can confidently say: game. changer.I use my cooler every single day, whether I’m going to work, running errands, or even just spending time away from my home base. It keeps my milk at the perfect temperature for hours (even in the summer heat!), and I never have to worry about spoilage or rushing home to refrigerate.What I love most:Insanely convenient: No more juggling bottles or hoping a friend’s fridge is available.Peace of mind: I know my hard-earned milk is safe and fresh.Perfect size: It fits several bottles/bags and doesn’t take up a ton of space.Discreet and mom-friendly design: No one even knows it’s for milk — it just looks like a regular cooler!For any other mamas who are exclusively pumping, especially if you're back at work or just constantly on the go — this cooler is 100% worth it. It gave me back freedom, flexibility, and confidence. Honestly, I don’t know how I managed without it.

I honestly can’t say enough good things about the Ceres Chill OG Breastmilk Chiller. As a breastfeeding mom with a busy schedule, this has been one of my most-used (and most-loved) baby items—and it’s not just hype. It’s beautifully designed, extremely practical, and solves so many of the common frustrations that come with pumping on the go.⸻🍼 FUNCTIONALITY THAT MAKES SENSEThe biggest standout feature for me is how versatile and convenient it is. Whether I’m pumping at work, in the car, or while traveling, I no longer need to lug around a cooler, ice packs, or a dozen extra bottles. You can pump directly into the chiller, store your milk, and it keeps cold for HOURS. I’ve gone 12+ hours with it staying at a safe temperature without any issue. Depending on how you configure it (ice in the outer chamber vs. inner), it can chill for even longer.I was skeptical at first, but after the first use, I was hooked. The stainless steel construction keeps it sturdy and insulated, and it’s compatible with most standard breast pumps, so I don’t have to switch up my routine or buy extra parts. It’s also leakproof—something I was seriously concerned about—and I haven’t had any spills or condensation even after throwing it in a bag and heading out for the day.⸻✈️ TRAVEL-FRIENDLY & TSA-APPROVEDThis chiller has made travel so much easier. I’ve flown multiple times since having my baby, and getting breastmilk through TSA is always a stressful part of the journey. With the Ceres Chill, it’s one discreet container that holds everything safely. TSA has never questioned it, and because it’s compact and non-electronic, there’s less hassle during security checks. No separate cooler or ice pack explanation needed!⸻💅 DESIGN & DURABILITYCan we also talk about how pretty this thing is? I got the Mombré color and it’s gorgeous. It looks like a high-end water bottle, not a breastmilk chiller, which I appreciate when I’m out in public or at work. The quality is top-notch—the stainless steel feels thick and durable, and it doesn’t have that “cheap metal” feel or smell. The cap is sturdy and secure, and there’s a silicone seal inside that keeps everything leakproof.⸻♻️ SUSTAINABLE & LONG-LASTINGAnother major plus for me is that it’s reusable and eco-friendly. No single-use plastic bottles, no throwing out melted ice packs—it’s a small change that actually makes a difference. I also love that the company is woman-founded and committed to safe, sustainable design. The materials are BPA- and DEHP-free, and it comes with a lifetime warranty, which says a lot about how confident they are in the product.⸻🔄 A FEW THINGS TO NOTE• Lid threads can be tight: The top can feel stiff to unscrew, especially if you overtighten it. Once I learned to close it just snug (not super tight), it became a non-issue.• Not dishwasher safe: This is clearly labeled, but worth repeating—it’s hand-wash only. It doesn’t take long, but it’s something to keep in mind if you prefer tossing things in the dishwasher.• On the pricier side: It’s an investment, yes—but if you pump regularly or travel, this pays for itself quickly in saved time, bottles, and peace of mind.⸻🏁 FINAL THOUGHTSThe Ceres Chill OG Breastmilk Chiller is one of those rare products that truly lives up to its promises. It’s smart, stylish, and extremely practical. Whether you’re a working mom, traveling, pumping at night, or just tired of juggling a dozen bottles—this simplifies your routine without sacrificing safety or quality.I wouldn’t hesitate to buy another one or gift it to a fellow mom. It’s one of my top must-haves for breastfeeding and pumping, and I genuinely feel more confident and less stressed every time I leave the house with it.Highly, highly recommend.

Love it! Why? Listing pros and cons below and will list some tips at the end. Hope it helps. In short, I do think that any good Thermos could do a great job as well if you have access to a fridge at work and that is where you intend to use the chiller. If you need to chill milk without a fridge, read on.Pros:- It eliminates ice packs to chill pumped milk in absence of a fridge (great for the forgetful, tired mom ;)) and you don't have to travel with a bunch of bottles. I feel it is way easier to handle. I used it this way mostly when traveling, not so much at work (where I had access to a fridge).- Stores milk COLD. (Keep in mind the inner chamber only holds 12 oz! 24 oz if using inner chamber for ice and storing milk in the outer chamber. Still nice and cold, but less so than with the milk in the inner chamber.)- Can be re-used as a Thermos when done pumping!Cons (not really, just inconveniences for me):- Inner chamber only holds 12 oz. Not enough for a work day's worth pumping for most moms. Even when using the inner chamber for an ice/water mix and filling the outer chamber with milk, that is only 24 oz (possibly 25, but that's cutting it really close when screwing in the top). If you have access to a fridge, you can store about 34 oz in the bottle and it says cold enough on the way home even without ice.- Price is a bit steep for what it is, especially if you aren't using the ice chamber as intended. But it is versatile and I did make use of all options over time.- The direct pumping option doesn't work well for me (didn't seal well) and isn't really practical due to bottle size and the need for two chillers if you want to double-pump!Tips:- Let your milk come to room temperature after pumping and before pouring into the chiller (if you can). It definitely helps keeping the ice longer.- The inner container is small (12 oz). So, likely too small for a whole day's worth of milk. I often used the inner chamber (filled it with ice chips and added cold water from the fridge) to chill. 24 oz of milk can be stored that way. That still was not enough for me most days (I have twins and easily pumped 40 oz during a work day). I have also used the chiller without ice since I do have access to a fridge at work (about 34 oz can be stored this way). I just pumped into some regular bottles and "dumped off" into the chiller. The milk stays cold enough on the way home if it was kept in the fridge during the day. I left a pump and a whole set of pumping parts at work, stored in the fridge between pumps and cleaned at the end of the day - dried over night at work. (Works well if you have access to a desk or a locker, a sink, and a fridge).- You will get some milk fat stuck to the inner chamber if you filled that with ice. Also might have a milk fat "ring" if you just stored milk in the bottle in the fridge. That is perfectly normal and happens to any breast milk storage container. Just leave a little bit of room in the bottle, make sure the ice chamber and the top is sealed well, tip over and swirl/gently shake for a bit to re-suspend the milk fat before pouring out.- I used several 32 oz Mason Jars with pour lids to store milk at home (poured into those directly from the Ceres chiller when I got home from work). This allowed for easy pouring of bottles for our nanny while I was at work and doesn't create a bunch of plastic waste from bags. If you prepare bottles for day care the night before, you won't need extra storage - just pour directly into the bottles that go to day care!- Obviously, if you want to freeze milk on a routine basis, you still need a system for that. Consider "milk sticks" or "cube trays" and large freezer bags for that. That will cut down on the plastic waste as well.Good luck, pumping momma! You are doing a fantastic job for your baby! It is HARD work and a LOT of commitment. Make sure your family appreciates and actively supports your hard work and dedication! Pump on, momma! You've got this!
