Some time ago this issue was discussed and at the time I was searching for new covers, wanted to replace a set I'd had since 2008 or so, originally produced by an outfit called Alan-Graham Motoring. Despite a rather clunky lower cover attachment arrangement their durability was impressive. I chose Cordura in black, paid a whopping $190 which was a small shock but over time that's proven to be a good investment. I STILL have that set and they'll soon find themselves in another van I'm keeping for various duties.
FF to 2017 and after considerable searching found that same outfit again BUT their prices had ballooned to a bit over $300 for the same set, shipping adding almost another $50, that being from a host of BS issues they claimed forced them to charge that much. Wow---so the hunt began again and I found Decor Auto in Los Angeles. They were far far above any other outfit I'd contacted, sent samples without charging me, talked personally with Sue the owner---a match made in heaven.

The photo gallery is fun to see.
From mild to wild and everything in between they're as good as I've seen and IMHO very fair priced for great quality. They don't take a back seat to any other brand.
I highly recommend giving them a look see and if the mood strikes you support a smallish shop trying to do good work for fair cost and maximum customer satisfaction.
