For parents on the go and mommies with nice bags =) This zip up bottle cooler keeps milk fresh and messes contained. The case has a gel pack that keeps milk nice and cold, great for breast milk! It is nice and compact so it’s not like you are carrying a cooler around with you. It fits short and tall bottles up to 2″ wide. Easy to clean, just run the entire thing under the faucet.
