It would be hard to figure out the fakes without having a real pair beside.
I didn't really like the video, "the level of engineering and quality control . . .", what the? Having real leather matters a lot, both had enough stitching that assuming the thread wasn't crap (which they didn't test) that is a wash, the fake had a couple tiny cosmetic defects which doesn't matter to me, the foam and armor was a little better in the real one but at 3mm thick with a plastic load spreader I'm not convinced that matters at all. So for me the knockoffs are a solid do not buy because of pleather, but I doubt the rest matters. If the knockoff used leather and sold for $100 instead of $250 for the real ones, I would consider it (although I would rather have non-branded instead of a knock off).
