Using this dry bag is a piece of cake. First, put all your things you need for the ride inside the 12L dry bag. To secure it, take the built - in straps of the Rear Rack or Cradle and loop them through the dry bag's built - in loopholes. This will keep your bag firmly in place. When you want to access your stuff, use the quick - release system. It's very easy and fast. As for maintenance, since it's made of heavy - duty TPU and is fully waterproof, you don't have to worry too much. But after using it, it's a good idea to let it dry out completely. Don't overload it. The recommended load capacity is 4kgs (9lbs), so try to stay within that limit to keep it in good condition.
