The Coolest is not so much a cooler as it is a party companion. Just plain smart and practical. I have never in my life lusted after a cooler until now, probably because there has never been a cooler quite like this until now.
Not only is this cooler literally cool (seriously — it'll keep ice intact for 4 to 5 days), but it's also legitimately cool. It has a built-in blender, Bluetooth speakers, a USB charger, and a bottle opener, so it's essentially a party in a box. Plus, it comes in pretty sweet colors.
