2off old PC psu fans 80mm
1off 12v dc adapter recycled from something or other.
I discovered that the bare fan will zip into the ankle section and hold there pretty well.

So trousers on a hanger, one fan in each leg, leave running for a little while - sorted.

Will also work from a 12v lighter socket in a car/van... so no reason to have stinky leathers on track days.
