Air Conditioned Necktie Improved, Less Dorky

I told you back in August that Japan's Rare Mono Shop was selling a USB-powered necktie with a built-in cooling fan. Now, they've come out with a 2.0 version. The new version is more stylish, more discreet (no more air grate on the knot -- it's now hidden), more controllable (it has an on-off switch) and MORE PORTABLE (you can unplug and run on battery power).
