This is a Vango 60 litre rucksack. It's mostly in excellent condition because it hasn't been much used, but it's old and the internal waterproof coating has deteriorated. This could be recoated, for example with a spray product, and instructions can be found online, e.g. https://youtu.be/DXCHdbYzsTY?feature=shared.
Please say when you could come for it, and don't just say any time! I live near Lancaster railway station.
