Coolers for Breastmilk

Hi ladies! Does anyone have recommendations on a cooler to transport breastmilk in? I'm exclusively pumping and will be traveling 3 hours one way to the airport to pick up my mom and at least 3 hours back. During that time I am going to have to pump at least twice if not 3 times depending on if we make stops. Each time I pump I am filling up 2 5 ounce madela bottles... I will also be taking some breastmilk with me for my doctor to eat before I pump. So I am going to need a goo size cooler. Any recommendations are appreciated! Even better if I can order if off of amazon and have it delivered asap! 😊😊
