We are a family of 3 and live in an area where 100 degree temperature is commonplace during the summer. We needed a cooler that’s not so big and heavy, and for which I am not carrying a whole day’s worth of food- just some snacks and drinks for a walk in the park or at the zoo . This little backpack is perfect and fits nicely on my back. I am 5”2’. A little pocket in front of it fits my phone and car key. Can’t wait to go to all the adventures with this little backpack.
