If you're a photographer looking for some cold ones after a long day, you should have Poler's combination camera bag cooler.
It fits a DSLR lens as well as other accessories, but if you'd rather be partying, you can take out the padded dividers and use it to keep your brews cool. Or soft drinks, if that's what you're into. It's $US50, it comes in black or orange, and it also has three straps so you can hook it up to your bike. [Uncrate]
