An elite cooler!
"This gets packed each morning and brought to work for 12 hours. It rests in a car and is south Louisiana so it’s quite hot. First few days I filled with ice to cool my drinks / lunch. Did great with minimal melting and no leaking. Since then, I’ve been packing with ice packs and it’s going fantastic. Only thing I don’t care for is how hard it is to unzip but it’s leakproof so I’ll shut up. Highly recommend!"
