Great at conduction, but with not a lot of thermal mass, meaning that actually your drink will usually just make whatever it's touching (your hand, often) super cold or hot.

    We’ve been storing and drinking beverages in aluminum cans for like a century now and this hasn’t been a big problem.

    It's a big enough problem that products are sold and even given away specifically to combat the issue.

    Also, the aluminum drink can was invented in 1959, and the koozie started becoming a thing in the early 70s. But I'm sure people were insulating their cans with DIY koozies before then.

    Did you know you can get pint glass koozies, just like for cans?

    Eg

    We also have those nice paper sleeves for coffee cups that would do the job as well. At least where you touch.

    So it’s an already-solved problem for this application.

    Sure but isn't it mostly for camping equipment? Don't really see why you would use it when strength/weight isn't much of a concern.

    I used to make, consume and share a lot of frozen beverages. I had a set of aluminum cups that I loved, but everyone else hated them because they started frosting over as soon as the frozen drink was poured in. My then girlfriend, now wife, would only use them with a towel wrapped around them for insulation.

    Oof. I think I lean more toward her side, to be honest. I don't like having cold hands.

    I didn't begrudge her the right to be warm, but it did make the cups look a lot less pretty. The ones I had were shaped differently, but basically this:

    I got them at a thrift shop, so no clue what brand they were. I think I technically still have them somewhere but have only used them once any time even remotely recently.

    If you're sitting in hot bleachers, the cooling effect on your hand or forehead is pretty nice, and you're gonna drink the drink before it's warm anyway. Hot is more of a problem unless you're cold enough to be wearing mittens.
