Neat idea ... but only IF you have a thermal sleeve for the canning jar. Canning jars are designed to transfer heat from the outside to the inside, and — hold on a sec, ,... yep,. just double-checked, — physics works in both directions. But if we're walking around with a Kozy on our Mason Jar, it defeats the purpose of looking utilitarian-kool.

Physics is to mainstream for hipsters. Hehe. You do make a great point though.
But if that chick with the plastic-framed glasses hand knits a rag-wool sleeve, the hipster is saved!
