OK Ron, a brief intro to thermodynamics and how it applies to kilts.
The first thing you need to understand is the differance between heat and temp. Heat is a physical property of all matter. All matter has heat (even if in very small quantities). Heat cannot be destroyed, only transferred. Temp. is the measurment of heat and its transfer.
Heat can be tranferred by three methods, Convection, Conduction and Radiation.
With a kilt what you are doing is insulating from heat loss. Your body produdes heat. That heat is lost thru the transferance of your heat through primaraly Radiation and Conduction. Your kilt collects that transfered heat and stores it. Willie feels warm because the kilt insulates from further heat loss and can transfer heat back by the same methods.
As soon as you lift your kilt, you no longer have the insulating kilt and heat loss is faster so willie feels colder.
So, it is heat loss thru Conduction, not Convection, that makes you feel cold. Kilt down = insulation from heat loss thru less air movement and absorbsion of heat and re-transfer back to your body. Kilt up = rapid heat loss thru large air movement whipping the heat from poor Willy.
Here endith the lesson.
