Using this Thule RoundTrip bike duffel is simple. First, open the wide - mouth opening. You can start by putting your helmet in the dedicated compartment. Then, place your shoes in the tarpaulin - lined shoe compartment. Use the lid pocket for your sweaty clothes or small items. When packing, try to distribute the weight evenly to make it easier to carry. For maintenance, clean the tarpaulin - lined shoe compartment regularly to keep it fresh. If the bag gets dirty, use a mild detergent and a soft cloth to wipe it down. Avoid using harsh chemicals that could damage the material. Store the bag in a dry place when not in use to prevent mold and mildew.
