Why don't Scottish men wear panties under the kilts?

Wearing pants is entirely optional. It is traditional that Scottish military regiments wore no underwear beneath the kilt and were routinely inspected by walking over a glass panel under which an officer looked to see that each man complied. Other regiments used a mirror on the end of a stick to obtain the same result. These days, probably the majority of men, especially young men would wear pants but more traditional men, myself included "go commando". As a kilt, made of 16 or 18 oz woolen cloth is quite heavy, in winter the upper legs are quite warm, so no underwear is really necessary, while in summer, being well ventilated, likewise there is no need. Occasionally, there is a danger of exposing oneself, if poor posture is observed when sitting, or crouching, but most kilt wearers are well aware of the dangers and are safely covered at all times.
