California-based company Couch makes guitar straps, camera straps, belts, bags, wallets and other gear from re-purposed vintage car upholstery. The products are all eminently stylish and don't look like they're used from upcycled materials; this speaks to the fact that the use of upcycled materials doesn't necessarily require you to compromise on style or functionality.
Couch's founder Dan Perkins started the company because he was unable to find a distinctive guitar strap that spoke to his sense of design. With California home to many auto-related businesses, Perkins figured that if he could get his hands on seat coverings and trunk linings, he could re-purpose them into guitar straps.
Despite the style quotient and high quality of Couch's guitar straps, they are very affordable, costing between $20 and $45. The company only uses properly stored original car upholstery and faithfully reproduced materials, and doesn't use material pulled out of wrecks.
