The Necktie Heater is a long flat flexible plastic heating element which can be inserted into a standard-sized tie, fitting full-length.
Since dress shirts provide no insulation from cold or wind, a heated tie can actively warm the neck as well as the core upper torso of the body. A scarf can be worn on top for further protection.
The deluxe model features a thermostat, cleverly disguised as a tie-pin, linked to a temperature-sensor in the knot area.-- FlyingToaster, Dec 07 2009 I'd use it for my feet.-- outloud, Dec 07 2009 electrically heated socks ?-- FlyingToaster, Feb 24 2010 random, halfbakery
