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 Timbuk''s magically transformed their Timbuk2 Classic Messenger Bag into a fully insulated cooler. It''s a bit Jeckyll&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.
