Do you like beer? Do you drink it out of a can? Do you like beer to stay cold when you drink it? Do you have $30 bucks to spare? Read on.

On our annual trip to REI to purchase unecessary items for our car camping trip, I spotted the Yeti Rambler Colster. It’s a Koozie for a beer. If you live somewhere with lots of bumper stickers you’ve probably seen one of these things. The Koozie was actually invented in Texas in 1980. I didn’t actually know that before looking at Wikipedia, but I had suspected Texas is a popular Koozie state. And interestingly enough the Australians (Reuben and Angus) call them "stubby holder”. I don’t know, but that seems kind of offensive.

It’s a sweater for your can of beer. The theory is that you are keeping it colder.

Usually they have clever sayings like this one

Well we all know that a Vacum sealed stainless steel solution will work better than a sleeve. This is why we drink coffee out of vacuum selaed mugs and water out of vacuum sealed bottles.

Beer is no different. It’s meant to be enjoyed at 40 degrees! Keep it that way please!

Enter the Yeti Cambler Colster. Perhaps the most expensive beer Koozie.

I would shower you with my scientific testing (yes the beer stayed cold for the duration of my consumption both indoors and outdoors) but Gizmodo has done all the heavy lifting in this review.

Need I say more?

They even have a nice decision tree to help you out

You can pick one up at REI for $29.99 or Amazon for a bit more since it appears there is a lot of demand.

★★★★★ Exceptional. A spectacular product.
