Just got it today and it's very important. Wanted to add my size report. I have a 40 waist and the large fits me. As mentioned, for a 40 waist, the large one has about 9 inches of overlap, so you'll need to bring that and velcro. When I zip up, the end of the strap lines up with the end of the velcro, so everything is fine. If you don't want as much overlap, maybe go for a medium size. With this type of product, I'd rather do more than less. The buckle appears to be solid aluminum, so it's light and strong. This belt will likely outlive all others, especially those made out of leather. It also seems great for hiking and camping as it doesn't go bad when it gets wet. Edit: Got the Light Duty model today and it seemed a little less wide. I measured both and it turned out that Heavy Duty is 40mm wide and Light Duty is 38mm wide. Not much of a difference when it comes to belt loops.
