I love this story and the pictures that come with it.
German company, Zirkeltraining, has taken disused 1950s gym euipment and coverted them into bags, laptop cases and wallets. What once was a pommel horse is now a holdall and the company also uses old gym mates and trampoline nets. Also as there really is a limited amount of this stuff available, the products are genuine limited editions and unique.
There’s also a video which shows you the bags which I’ve embeded below. It probably has a lot of good information in too but as I don’t speak German, I wouldn’t know.
