Let’s be honest here, thin fabric koozies are mostly useful for decoration; they don’t really keep a can cold for very long. This imposing metal Thermos contraption though? It’s the real deal.

Thermos’s stainless steel can insulator uses vacuum insulation and thick walls to actually provide a barrier between your beverage and the outside world. They go so far as to claim that it will keep a can cold for up to 3 hours, and even if that’s a little bit of marketing hyperbole, what could possibly be in that can that takes more than an hour to drink?

Over 1,200 Amazon reviewers have given the Thermos a 4.7 star review average, and you can get one (or more!) for just $10 right now, an all-time low. This would make a great stocking stuffer for the holidays, so check out before they sell out. [Thermos Stainless Steel Beverage Can Insulator for 12 Ounce Can, $10]
