Methods we DON'T recommend:
Having your bag dry-cleaned or putting your bag in a washing machine or dryer will void the guarantee and make your bag look funny. We don't want either of those things to happen. Your TOM BIHN bag can last for years. The fabrics we use to make our bags are treated with a water-resistant coating, but over time, that coating will start to dissipate. If you live in a rainy climate like we do, we'd recommend treating your bag with Nikwax after one year of use.
