This appeared to be a clever design when I was shopping for a durable belt and one from a well know company.  However, it's a "one size fits all" design, which means it was intended for people with a waist size approaching the equator.  That would not be so bad if there was a logical way to reduce the belt in length without cutting it and having to live with the frays forever.  Instead, they provided a movable loop to hold the excess length that for people like me with a 32" waist means running it all the way around to a mid-back position. That's just plain stupid.  So, I had to cut it down to size and live with the frayed ends picking up lint and getting caught in my equipment.  The so-called "double back" design is actually double trouble unless you're really rotund.  Don't buy it as there are much, much better belts on the market and at a lower price.
