I have some US camo rip stop trousers I wear for competitions as I don't care about messing them up or them smelling of people. My hunting clothes stay in a bag and are only worn at my shoots for the scent reason.

My missus being the glamour puss she is only has her hunting clothes that she'll lay down and shoot in so wears full on camo in comps.

I reckon it's more to do with having clothes you can muck up, thats what it is for me.
