I think our Canadian army and EMT pants have an interesting feature, the slotted buttons:
These are wind overpants, cotton nylon blend with the pockets actually only being slots so that you can reach the pocket of your normal pants underneath. It all depends on the conditions... The military makes durable clothing where style is second place to function.
I also have MEC River pants, they are very compact and lightweight nylon pants and bugs don't bite through them, ideal for the bush in summer.
