Been a few threads over the years on underkilts - if the term is new to you its like a cotton half slip that protects your kilt from you and still allows FREEDOM.

I started to notice that when I'm wearing an underkilt the wind still dances in my kilt's pleats but I don't get the kilt-in-the-face dynamic.

Not a physicist by far but I'm guessing what happens is that if the wind gets under a kilt when a man is wearing bifurcated underwear, or regimental, then the kilt acts like a sail and the wind makes all or part of it soar to the sky.

However if a man is wearing an underkilt the wind comes up under the underkilt but the underkilt prevents most of the wind from reaching the kilt and hence no high hemline effect.

I've reviewed my collection of kilts in the wind pics and I'm guessing an underkilt would have prevented the exposure in each case by -excuse the phrase - breaking the wind.

There are many kinds of underkilt - but my guess is any that are worn like a woman wears a half slip would have a similar effect.

Anyone else wear underkilts and notice something similar?
