WONDBORN 22Oz Portable Breast Milk Cooler for Outdoors
Description
24+ Hours Safe Chilling: Features an innovative vacuum lid and 720° vacuum insulation to keep breast milk below 40°F for up to 24 hours(Lab Tested), far exceeding other coolers. Meets TSA transport standards. Whether for a day trip outdoors or a long commute, it locks in the nutrition and freshness of breast milk, ensuring your baby can enjoy high-quality breast milk anytime.
Rapid Cooling: Four built-in high-efficiency reusable ice rings quickly lower the temperature to the optimal storage temperature of breast milk at 40℉ (approximately 4℃), rapidly locking in the active nutrients. No need for long waits; breast milk can be quickly stored after pumping, preventing nutrient loss due to temperature fluctuations.
22oz Individual Storage Bottles: Equipped with two 11-ounce individual storage bottles, the total capacity is 22 ounces, easily storing 5-6 pumps' worth of milk, covering the entire day's milk storage and feeding needs. The individual bottle design allows for separate storage of warm and cold milk, avoiding the risk of spoilage caused by cross-contamination, ensuring every sip is fresh and safe for your baby.
Detachable Design: The four ice rings can be separated and used independently. They can be combined for long-lasting freshness, or you can carry 1-2 ice rings with a baby bottle for short trips, significantly reducing the weight when traveling. Whether commuting to work or taking your child to the park, it can easily handle the task, eliminating cumbersome equipment.
Easy to Use: Simply freeze the ice crystal ring in the refrigerator for 12 hours to enjoy all-day cooling, no complicated setup required.Unlike other coolers that rely on tilting or pouring to remove the bottle(often leading to leaks or spills), WONDBORN features a flip-top lid design paired with a lift-ring baby bottle. This allows you to lift the bottle out with one hand, helping prevent accidental dripping or mess.
Multiple Cooling Methods: Not only can the ice rings be pre-frozen to meet the need for long-term refrigeration of breast milk, but for unexpected travel needs, ice cubes can be added for short-term refrigeration. It comprehensively considers the needs of mothers, completely eliminating refrigeration anxiety during unexpected outings.

- IFIveth F.Verified ReviewerRated 5 out of 5 stars2 months agoA Must-Have for Postpartum & Night Feeds
As a fourth-time mom, I’ve learned the small things postpartum make a big difference, and this cooler is one of them.
I brought it to the hospital while establishing breastfeeding and loved having a reliable way to keep milk cold without relying only on the hospital fridge.
Now I use it every night for feeds and rotate the ice rings so I always have them ready. It makes storing milk overnight so much easier.
The design is simple, sleek, and easy to use, and I love that it keeps freshly expressed milk separate from already chilled milk.
Overall, it’s been such a helpful part of my daily routine.
