I try to get at least two of each clothing item and some system to dry things out without burning em up. Army surplus pants aren't very expensive, usually. The fleece gaiters are not either. I focus on quite in stead of water proof. Obviously you can't dry out a rifle so three, four, five ,six of them are essential. Same with mules.
