These cardboard coolers are a must for any summer event: smart, green, recyclable and can fit 35 lbs worth of beer and goodies. It's like a cross between the heavy duty plastic coolers and the disposable styrofoam ones...but better.
The Cascades ThermaFresh cardbox coolers are made from 70% recycled cardboard and lined with a NorShield waterproof coating that not only protects it from the weather but also makes it reusable. The cooler can stay a frosty 41 degrees Fahrenheit for 36 hours in 70 degree weather, so the beers will stay chilled and the burgers will stay fresh. $15. [Cascades via Oh Gizmo!]
