I have a pair of Canadian Pattern 49 battle dress trousers, of wool, that are awesome! Stuff worn in Korea.
As a side note, during WWII, the Canadian Pattern 37 battle dress was always the #1 sought after uniform of commonwealth forces. The fabric was said to be much better than the English made wool! WWII stuff is Hard to find now! But the Pattern 49 stuff wasn still around a few years ago.

"Come, shall we go and kill us venison?
And yet it irks me the poor dappled fools,
Being native burghers of this desert city,
Should in their own confines with forked heads
Have their round haunches gored."
