There's just no need for warm beer. It's a beautiful day in the park and you deserve to drink a cold one that's actually cold. Geez! So we've magically transformed our Classic Messenger into a fully insulated cooler. It's a bit Jekyll & Hyde because it looks and feels like a messenger but performs like a cooler. Its waterproof TPU liner and total insulation keep the cold and the drips inside so you can stay outside. Did we mention it comes with a built-in bottle opener? Amen.
