I got these (brown and black) expecting a pretty ugly product given the material but I was pleasantly suprised.  They look nice, stretch well, but still give a firm hold.  There are no predrilled holes so they are infinitely adjustable. They show no signs of the center strip distorting or stretching where the metal prong goes through. It seems to seal back up after each use with infinite self-healing ability. I ordered and use them for workpants since I do a lot of handy-man jobs and am constantly bending and twisting.  I can highly recommend them for comfort and function.  I highly recommend them for both comfort and utility.
