Product Details
  • 360° Pro Cooling with a 316 Stainless Steel Ice Core:
Built around a food-grade 316 stainless steel chilling tube, this breast milk cooler provides 360° cooling without loose ice coming into contact with or diluting the milk. Simply freeze the core for 12 hours and insert it into the cooler to keep milk cold for up to 24 hours while traveling. With no melting ice or extra mess to manage, it offers a convenient way to carry milk for moms on the go.
  • Two 22 oz BPA-free Bottles with Broad Compatibility:
This bottle cooler includes two 22 oz BPA-free bottles that fit most baby nipples, so you can store and feed from the same container without transferring the milk. The two-bottle design also lets you keep milk from different pumping sessions separate. For overnight pumping or workday use, simply pump, cap, and go. The bottles are also compatible with most portable bottle warmers for more convenient feeding.
  • Advanced leak-resistant Construction:
The one-piece stainless steel core in this cooler for breast milk uses a silicone sealing ring to create a secure, airtight closure. Compared with plastic cores that may crack or leak over time, the stainless steel construction is designed to withstand freezing, accidental drops, and everyday wear. It also resists plastic aging and odor absorption, giving you greater confidence when carrying milk away from home.
  • Military-Grade Durability:
Drop-tested durability and Dishwasher-Safe Cleaning: This breast milk chiller was tested for 24 hours at -4°F, subjected to 4 ft drops onto concrete, and put through 20 dishwasher cycles. During testing, the unit showed no cracks, leaks, deformation, damage, or loss of cooling performance. Because it is dishwasher safe, you can clean it without additional hand-washing, making daily maintenance easier.
  • Custom Carrier Strap for Hands-free Travel:
This portable appliance includes a heavy-duty strap for easier carrying away from home. Securely clip it to your diaper bag, stroller, or another travel bag instead of relying on a thin carrying cord. Whether you are commuting, shopping, or keeping up with a toddler, the strap helps keep your hands free while making the cooler easier to carry.

FAQs on Grownsy Breast Milk Cooler

Up to 24 hours is the CDC guideline for expressed milk in an insulated cooler with frozen ice packs. This portable breast milk cooler is designed to keep milk chilled for over 24 hours after its 316 stainless steel core is frozen for 12 hours; treat that product claim as a maximum under tested conditions, minimize opening, and refrigerate, freeze, or use the milk promptly at your destination.

A properly prepared cooler can cover commuting, pumping sessions, and the return trip when milk stays continuously cold. Grownsy's frozen 316 stainless steel core provides 360° cooling without loose ice, while 2 included 22-ounce bottles hold multiple sessions. Label each expression time and move the milk to a refrigerator as soon as practical rather than extending storage simply because the container still feels cool.

Freeze the Grownsy stainless steel cooling core for 12 hours before use so it can deliver its stated over-24-hour cooling performance. Place it in the coldest part of the freezer and confirm it is fully frozen before loading milk. Shorter preparation may reduce the useful cooling window, so build refreezing into your nightly routine before a workday or trip.

Yes, but cool freshly expressed milk before combining it with already chilled milk, use clean containers, and date the pooled milk by the oldest portion. This set includes 2 large bottles, making it easier to keep sessions separate rather than adding warm milk directly to a cold batch; follow current CDC storage guidance and any instructions from your lactation or medical team.

Use a reliable food-safe thermometer when the trip or conditions make temperature uncertain; touch alone is not a dependable safety check.

• Keep a record of when the milk entered the cooler and how often it was opened.

• On this model, the sealed core is designed for prolonged cooling, but if milk becomes warm or you cannot verify the storage conditions, follow CDC guidance and err on the side of discarding it.

Check the liquid temperature before feeding, even when a precise setting or indicator is used.

The container may physically hold prepared formula. However, formula follows different preparation and storage rules from expressed milk.

Use a clean, sealed bottle, keep it properly chilled, and use refrigerated prepared formula within 24 hours; after feeding begins, discard leftovers within 1 hour. Avoid mixing formulas or storage routines in the same bottle, and clean the Grownsy cooler thoroughly between uses.
