    I think it will be substantially heavier!

    No thermal insulation also a big minus in my eyes. Missed the vacuum insulation part…

      They need to vacuum insulate because heat conductive metal would be a stupid choice of material, as opposed to glass or plastic.

        Etsy vendor comes up with a Fancy Woven Wool Insulating Sheath, in Many Colors, in 3, 2, 1… I end up using a sock.
