I was thinking of the knee and shin material on the HOG suit that is different than the knee material on the Edge suit. The suit has pads whereas the HOG suit has additional material that is slick and has more of an armored texture.
The HOG suit also has more material on the seat, velcro or zipper pockets installed, wrist seal cuffs, neck warmer, and zipper cover. Pockets can be zipper or velcro. I dive cold water and prefer zippers. My OS suit had velcro and I found them harder to use with gloves.
When you start addding up the individual extra components you see where the price difference comes from. Yet at the map prices either suit is still a good deal. A dry suit is expensive there's no doubt. But for coldwater diving the benefits make it worth it. And long term if the suit is properly cared for it can last ten years or more. Seals would need replaced from time to time but for me it still makes more sense than diving wet. I know people who simply would not be able to dive more than two months out of the year locally and not be comfortable all the time even then due to thermal issues diving wet. The dry suit took their season to seven months and they are warm and comfy throughout.
The suits are new. There are more and more out there. But they are made by a company with many years experience making them. I have had my suit next to those from several other mfg's costing sometimes thousands more. And I see no difference in quality or more importantly function. In some cases it's been better than those costing quite a bit more.
