I've had this for about three years on two bikes.
It definitely is very girlie, but if you don't tell, no one will know.
Best bit of kit.
Extends the riding season right through December/January in Scotland.
Jack Plugs available at BMW or Ducati shops. Maybe Hein Gerrike too.
There is an optional temp controller which works by switching the power to the garment on and off through four pulse settings My two mates and me just switch off if things get to cosy.
Wear the garment on top of a single layer, (T shirt) inside your jacket so the heat transfer is most efficient.
It's becomes part of your kit and will be there to comfort you on those colder days and nights.
It even has heating elements which go around your neck!!!
I paid about £100 but it has repaid itself handsomely
