This Wooden Belt by You and Me The Royal We, a Brooklyn-based company, is actually made of leather and bark. It isn't just appropriate for treehuggers and lumberjacks either and modern man could wear this wooden belt with pride.
The leather is printed to mimic wood graining in a two-tone brown. The buckle is a hefty piece of real bark but if that's not your thing you can also have a simple brass buckle. The whole Wooden Belt shebang with bark buckle retails for $90 ($58 with the plain brass buckle).
