I came across this while looking for some type of cooler to store bottles and diabetic meds in.. I had been searching for something that suited what I was looking for for weeks, until I found this. And its been an absolute lifesaver.. Can pack a bag lunch for the zoo or park or for the drive in movies. Or a day out in the sun watching one of the kids softball tournaments. Or for road trips, which is originally why I bought it, it keeps the bottles cold. and medication that needs to be refrigerated cold.. I love this. Definitely av great investment.
