The weak link in militarty belts is the adjustable pin.  When that wears out you have to replace the whole buckle. With the thomas bates desigen, they have eliminated the problem, with a better mouse trap.  There are no moving parts per se to wear out.  This belt uses an anvil style buckle which makes closing the buckle on the belt much easier.  Please Note this belt has also upgraged the belt material, which should last much longer, and dry, if wet, much faster. You can find military style belts cheaper, but you won't find any better.
