Breastmilk Cooler Travel Bag for Momcozy/Medela/Elvie/Willow Breast Pumps - Insulated Storage Bag with Ice Pack & Waterproof Mat - Portable Breast Pump Accessories for Working Moms & Traveling - Perfect for Office, Commuting and On-the-Go Use

I use this bag to pump at work. I purchase two additional flat ice packs (Titan 250g Ice Packs), place the provided on at the bottom, and the flat ones on the sides of the insulated area. It keeps my milk nice and cold all day, even though the milk is going in warm. I can fit 1 small Medela bottle which I use for measuring, and whatever bags I pump during the day. Both of my pumps fit snuggly in the pockets but are still easy to get out. I keep extra milk storage bags, a marker, and a charger in the netted zipper inside, and I keep my keys in the pocket on the outside so I can’t forget it at work. This fits everything I need perfectly and is fairy compact. It holds its cube shape well, and people compliment my “lunch bag” when they see it. It has everything you need, nothing extra, and is excellent quality.
