Something that I understated earlier is the need for a pair of stout work gloves. These need to be lightweight and well fitted for dexterity in tight places, but they need to afford a good degree of protection against brambles, spider and insect bites and oogy stuff. I have a pair of cheap work gloves from OSH, but I am definitely considering something a bit more leathery, though that is purely aesthetic on my part. Additionally, because you will likely not want to wear your gloves all the time and because they tend to take up a pretty substantial amount of pack space, you might want to get a pair that clip together. That way they can be slung from a hook or ring on your pack.
