I picked up a set of five Bundeswehr trouser belts (hosengurtel) off the "surplus market" just before we left for Burning Man. These belts are great! Metal buckle, heavy leather, adjustable up to about a size 32" waist, very euro-sleek! Four of the belts have silver buckles and one has a gold finished buckle, which I presume is an officer's belt, but I'm not certain.
The belts fasten with a tab and hook system that gives them a very sleek look with no belt end sticking out from the buckle.............. These are the narrow width belts meant to hold up your pants, not as a gear belt or outer belt.
