I purchased this because I wanted a small cooler for one or two bags of milk for outtings. Its Bigger then I thought it would be based of the pictures. But not so big that its a full size cooler. I easily put 10oz frozen of medela bags (3bags total) and it zipped just fine. I did have to fold down the top tab where the date is but no big. Other brand bags might fit differently. I could also see how you could cut one one side of the cooler to get more room. It would leave the one side with the insulation stuff though. There is a plastic covering over the cubes I imagine just in case the cubes leak. All of the inside would wile down very nice if breaskmilk leaked at all-edit to review. Meleda storeage bags do not fit well. They are a bit wider then the zipper. You can fold, but I found the avent bags fit better. Read more

Perfect small size for storing milk when pumping on the go. I used it for a day trip and decided to start using it for transporting my milk home from work each day. Today I fit 3 full and one partially full Lansinoh storage bags. It looks like it would fit about two full kiinde bags too. It doesn’t stay frozen as long as I’d like it to, but I have a shirt commute and a fridge at work I can leave it in so it works for me. Good purchase. Read more

This is really convenient to use. The ice part is not removable and freezes solid. It needs to be frozen flat and open to be most useful. The zipper is a little hard to zip around...it's more because if how it the pack is sewn than the zipper itself.I use it to transport frozen breastmilk. It fits Lanisoh breastmilk bags. I store anywhere from 2-4 ounces of milk in each bag and the pack fits 2-4 bags depending on the amount of milk. I think the most I've been able to put into the pack is 9 ounces (three 3 ounce bags). It lasted an entire trip to the ballpark. It's great for a day trip. The milk thaws completely (no frozen icicles) after 3-4 hours but stays really cold for a while. Read more

This zip ice pack is great! Currently using the Kiinde breast feeding kit for my son and this zip pack freezes fast, fits 1-2 pouches of milk and keeps them cold for hours while we're out of the house. The size is ideal to slip into a diaper bag or purse and not have to lug around a cooler or bug insulated lunch bag. Read more

We used this to store breast milk on the go. We were able to store two kiinde pouches. It was a tight fit but manageable. It kept it cold for the day and fit nicely into my wife’s purse. Recommend this over other options if looking to keep breast milk cold for the day while on the good Read more

I have enjoyed this. I can store two Medala bags with about 12ox between them. They seem to be packed with water so they little packs inside are usually not frozen completely by the end of the day, but still cold. They last me about 11 hours from leaving home to getting back and unpacking. Read more

OMG I cannot recommend this enough! I purchased this to travel with my Kiinde breast milk pouches for my daughter to be able to make her bottles while on a short trip and I immediately fell in love. All I would wish for this is that I purchased it sooner. Fit one 8oz pouch and I'm sure you can fit two 4-6oz pouches. Still frozen after 5 hours with only 1 cube melted. Read more

Super convenient and compact. I don't have to whip out a lunch box to store my milk while at work. I fit about 3 -5oz Lansinoh/Avent/Honeysuckle bags but I am sure I could fit more provided the liquid is disbursed evenly through the bag. I just wish I didn't have a hideous giraffe print. It was the last of a kind so I had to get it. Read more
