Reason for the prices? They seem to business with companies like theirs - innovative with a social and environmental conscience, and at relatively low production runs. California labor is way more expensive than China labor, but California employees aren't exploited/abused by their management - the state won't allow it. Even if they did, I don't expect FM is that sort of company. I investigated that expensive bag - they teamed up with Mafia to produce it. Mafia produces products from "upcycled" materials - sails. Check it out: https://mafiabags.com/pages/welcome-to-the-family. Custom design, low production runs, socially and environmentally responsible companies - of course it's "expensive." I don't expect you will see it on alibaba - maybe possible, but the the sales volume probably isn't high enough to lure in low cost competitors. I don't think my OW needs a bag, but if I do need one, I'll be happy to get it from OW - or stuff it in a large gym bag if I don't need a custom fit.
The fender? Their are others available for the OW - but more expensive.
