Winter Clothing in 1st century AD legionary re-enactment

[Kegluneq]

But aren't you doing doing exactly that, and transposing most modern westerners' preference for trousers in cold weather onto "a hardened, beaten up, legionary who could probably eat dirt and ask for seconds"?

There is an excpetion - kilts. Many wearers don't even use underpants. Kilt wearers at this forum link complain mostly about cold ears and hands.

There's also the 50% of the population who have probably at some point worn skirts outside in snowy weather. I know many girls back at school didn't seem unduly discomforted by wearing knee-length skirts (or shorter!) in winter...
