A hipster that prefers flannel or some type of long-sleeved overshirt with a "lumberjack" or tartan design, has a beard and "nerdy" black glasses, is probably tattooed, and who has extensive knowledge of single-speed bicycles. A blend between a hipster and a dirtster; more the former than the latter. The northwoods hipster is quite popular in Minneapolis, MN. They are typically spotted at organic foods stores such as Whole Foods.
