I am no expert in a technical sense but have been adventurous with belt purchases over the years. My Zegna, Dunhill, Bally, and all such branded belts have come apart soon enough for me to wonder if these guys choose the right OEM partners. Dunhill's buckles are terrible as I've seen with two of them, and these babies cost 400 bucks in retail. Boss is as always one of the poorest in quality.
And yet while in NY six years ago a colleague took me to Century 21 and I bought a couple of 'Donald Trump' belts - his apprentice show was popular so on a whim I bought the two. I've worn the bejesus out of those belts and they are sturdy as always. Even the belt holes are perfectly fine. None of the usual cracks and nicks and unhinged buckles.
