Portable Breast Milk Cooler

At 4AllFamily, keeping things cold isn’t new to us — it’s what we do best. For years, we’ve been designing medical-grade travel coolers trusted by thousands of people whose life depends on refrigerated medications.

With MilkyWay, we’ve brought that same expertise, testing standards, and uncompromising reliability to breast milk — because your baby’s milk deserves nothing less.

The MilkyWay Breast Milk Cooler uses 2 high-performance Biogel cooling packs combined with a high-insulation stainless steel body to maintain a safe refrigerator temperature of 36–46°F (2–8°C) for up to 24 hours, when used as directed.

All of that without electricity, without leaks, without hassle and, above all, without compromise on your baby’s safety.

We know. Breastfeeding. Pumping. Working. Traveling. Parenting. Sometimes all in the same day — sometimes all before lunch.

The last thing you need right now is a complicated cooler or mini fridge to figure out. That’s why we made MilkyWay as simple as possible:

1️⃣ Pour your expressed milk into the bottles
2️⃣ Grab a frozen Biogel pack
3️⃣ Place everything in the cooler
4️⃣ Close the lid — and go

That’s it. Really.

No tiny parts you’ll lose in the bottom of a bag. No buttons you’re afraid to press. No 100-page manual you’ll never have time to read.

MilkyWay uses passive Biogel cooling, so there are no cables, no batteries, and no power required. It just works — making it ideal for breastfeeding parents who pump at work, travel, teach all day, commute, or simply spend more time out than at home.

When it comes to your baby, safety isn’t optional — it’s everything.

MilkyWay is designed with temperature safety and material safety in mind. The outer bottle is made from 316 food-grade stainless steel, a high-quality material commonly used in medical and food applications. It’s durable, safe, non-reactive, and easy to clean.

The included milk bottles are made from Polypropylene (PP), a BPA-free, BPS-free & phthalate-free material that is FDA and EFSA-approved for food contact. And importantly, the Biogel cooling packs never come into direct contact with the milk, eliminating any risk of contamination.

By maintaining a stable, safe temperature throughout the day, MilkyWay helps preserve the freshness, taste, and nutritional quality of your breast milk — so you can focus on your baby, not on breast milk storage anxiety.

MilkyWay is designed to fit seamlessly into your routine — even after you get home. The included bottles are freezer-compatible, so you can place them directly in the freezer if you need to store your milk frozen for future use. Just remember not to fill them more than ¾ full, since milk expands when freezing!

And when used without the cooling packs, the thermos bottle acts as an insulated container that helps keep breast milk warm and protected from outside temperatures — a surprisingly useful feature when traveling with your baby or feeding on the go.

One cooler. Multiple uses. Fewer things to carry.

We made MilkyWay simple — but not “dumb.”

The built-in temperature display lets you check the internal temperature at a glance, without opening the cooler. That means less temperature loss and more peace of mind. You always know exactly where your milk stands, in real time, shown in both °F and °C.

For added protection, especially in hot climates or during long days out, MilkyWay includes a thermal insulated carry bag that adds an extra layer of insulation and makes transport even easier.

MilkyWay comes with two baby bottles, each holding 11 oz (330 ml). Together, you can carry up to 22 oz (660 ml) of breast milk at refrigerator temperature for up to 24 hours.

The bottles are made from Polypropylene (PP), a material that’s BPA-free, BPs-free, phtalate-free, and approved by the FDA and the EFSA for food contact. They’re compatible with most wide-mouth breast pumps, so you can pump directly into them — no extra transfers, no extra mess, no milk loss!

They also work with most standard baby bottle nipples, and we include three nipples with the cooler, one for each age (0-3 months, 3-6 months, 6+ months), just in case.

Prefer using your own bottles? No problem. MilkyWay fits any container with an outer diameter of up to 2.6 inches (6.7 cm).

Slim, lightweight, and easy to carry, MilkyWay fits comfortably into diaper bags, backpacks, or its insulated carry bag. The top handle makes it easy to grab and go — and yes, it’s nice to look at, too.

This portable breast milk cooler is TSA-compliant, and breast milk is allowed through airport security in quantities larger than standard liquids, even if your baby isn’t traveling with you. It’s considered a medically necessary item.

Just make sure your Biogel cooling packs are fully frozen when going through security, and you’re good to go.
