The double D fastener is a simple and effective way to fix the belt and offers continuous adjustment to any desired size. The belt itself is thick and durable with minimal stretch and fits all the pants I've worn it with and the webbing is slightly beveled at the edges to reduce the chance of fraying and still be comfortable if you wear it for long periods of time sit in the car. or otherwise bent. Maybe not ideal for holding a lot of heavy stuff if you have an EDC, but for general "trouser and multi-tool support" work it looks snazzy and works great.
