It’s season for warm-weather drinking is upon us, so keeping a beverage cold becomes a priority. These are double-wall, stainless steel, vacuum-insulated coozies for 12-ounce beer or soda cans.

They work on the same principle as regular Thermos bottles. I have been using them for years.

The good:

– They work much, much better than foam or plastic coozies. They will keep a beverage cold for hours.

– There is a silicone ring around the opening that gently grips the can, holding it steady and sealing out air, while still allowing you to slide the can in or out easily. The ring also provides a handy grippy area.

– They prevent condensation from dripping onto your fine furniture, workbench, table saw, etc.

– They have a hard plastic base that will not mar a nice finish.

– They do not wear out. They are seamless and plugless. I suppose you could put them in the dishwasher, though I have never had reason to. A quick rinse is generally enough to keep them clean.

– They are designed to allow easy drinking from the can. They do not reach high enough to block the can opening.

– They are cheap: they go for $10 on Amazon. Yeti makes a similar one that is three times as much. Other brands go for perhaps $15 or $20. There are cheaper ones, like the $6 Coleman, but they are are simple plastic or rubber, and aren’t as effective.

The bad:

– Though you can fit bottles inside, and though these coozies will still help keep the bottles cold, the bottle will move around a little inside, and won’t stay as cold as a can would. Of course, that is true for most coozies.

– They are rigid, and slightly heavier than a foam coozie. So a soft foam coozie is probably better for backpacking.

– Though I have never done it, I suppose it is possible to crush one. Stepping on the side might not do it, but running over it with a car probably would.

So. Cheap, effective, well-designed, long-lasting. What more could you want?
