Pretty much what I do, and just deal with the odd chips that make it around the back of the chaps....Not sure how it works in the States- but you need to be sure whatever you decide to wear meets the minimum requirements for the forest, possibly State and employer rules and regulations.
Be aware, light well ventilated and easy articulated trousers are often designed for climbers and are not rated high enough for ground work (under possible rules and regulations for where you work).
Over here, in Summer- most pro loggers wear shorts under open back chaps- so the backs of the legs are exposed as such- unimpeded air flow.
