I've been rocking the same fabric sport loop band since launch day for the series 5 four years ago. It's been incredibly durable, and the Velcro still holds fine. There is some very minor fraying along the edge of the band in a couple of spots, but much less than I'd expect after four years of continuous wear. With Apple's pivot to carbon neutrality, I've read that the new sport loops are made with a lot of recycled material including discarded fishing nets, so I can't say if they'll wear the same. They are incredibly comfortable. I just chose the Nike sport loop for my new series 9.
