The Rise of Crazy Koozie Technology

If you're still using those neoprene fabric or foam insulators to keep your beers and sodas cold, you're pretty much wasting your time. Sure, they're available in just about every design and color you can imagine (see Chewbacca example below), and they can even be customized if said imagined design doesn't exist. But as far as doing the job of keeping your drink cold, they fall flat.

Now let's talk koozie technology. (Yes, it is a thing these days.) Tech types have taken on the formidable task of creating koozies that actually keep drinks cold — and succeeded. Now you can thank these three makers (for starters) for saving you from any more warm beer at your next tailgate.

Thermos has been doing insulated beverages for a long time. The company was founded in 1904 and has been making everything from lunchboxes and coolers to water bottles and tumblers. But pop your beer in the Vacuum Insulated Beverage Can Insulator and it will stay cold 10 times longer thanks to the double-wall vacuum insulation. That's what they say, at least. And at $9.99, even if it keeps a beer ice-cold for an hour, that's plenty long enough, right?

Ever heard of the ColdCan? Probably not. It was just funded through a Kickstarter campaign in July 2015 and uses space-age technology and a sleek design to keep cans cold. The guys at ColdCan use a ton of techy terms like Cryogel (an insulation technology similar to one used by NASA) and PolyPro as what they say makes ColdCan "one of the most advanced thermal insulating technology known to man." True? Who knows, but at $20, it does look good, and if it can (ha!) keep your beer cold, it's a winner.

Yeti coolers came onto the market in 2006, and the Tundra coolers have pretty much set the standard ever since (they're grizzly proof, for goodness' sake). So it's not a big surprise they also applied that killer technology in a smaller package. The Yeti Rambler Colster  ($29.99) is made of stainless steel and has double-wall vacuum insulation (there's that term again), so it will still keep your drink cold or hot. And it's Yeti, so ... you get the idea.
