Military Box Pleate Canvas Kilt?

[cloves]

all of alanH's x-kilts are box pleated. They are typically made of something other than wool. Yes the pleats are sewn in though.
My corduroy Star kilt is box-pleated, with the pleats sewn in.

Thanks cloves, but I can tell now that I really don't know enough to be thinking about these things.
