On a shelf in one of my closets lies an article of clothing I hope never to need again. That is a version of the world's warmest hat, the Astrakhan Ambassador, perhaps Russia's only contribution to classic mens clothing and a regular atop my head on winter days in America's midwest years ago.
Usually seen in black or gray Persian lamb but available in more esoteric furs such as mink, the Astrakhan keeps a head toasty on the coldest of days while its built-in ear flaps do the same for those vulnerable extremnities. It is frankly too much hat for genteel commutes by car or train, but comes into its own on a ten block subzero walk across town when an ordinary fedora fails completely.
If only there was some equally effective covering for the nose.
