Using your Basil Navigator Storm frame bag is easy. First, decide whether you want to attach it to the saddle side or the handlebar side of your bike's frame. Then, use the (extra) Velcro straps to secure it in place. The anti - slip coating will keep it from moving around. When packing, you can put in a bike lock, wallet, and mobile phone. Just make sure not to overfill it as it has a 2.2 - liter capacity. For safety, the reflective logo on the side makes you more visible to others, especially in the dark. As for maintenance, since it's made of waterproof (IPX3) fabric and has a tarpaulin bottom, a simple wipe with a clean cloth will do if it gets dirty. This will help keep your bag looking new and ensure it lasts for a long time.
