What is it with old leathers? I’ve had to get my old leather jacket out as my Alpinestars zip failed and has been sent back. The leather jacket is c1991 and stinks! It spent 20 years hanging in my Mum’s wardrobe and I can’t have it in my house unless it’s in a plastic bag. My leather trousers are the same.
So what causes it and how can I stop it?
