Using the Eagle Creek Ranger XE 7L Crossbody Bag is a breeze. First, adjust the shoulder strap to your comfort. You can wear it on your right or left shoulder as you like. For easy access to small items like keys or your phone, use the quick - access zip pocket. When you're out and about, put your water bottle in the stretch side pocket and your jacket inside the main compartment. For more organized storage, use the interior zippered pocket for things like your wallet or cards. When it comes to maintenance, you can spot - clean the bag with a damp cloth. Avoid using harsh chemicals as they might damage the recycled fabrics. Also, try not to overstuff the bag to keep its shape. When not in use, store it in a dry place to prevent any mold or mildew from forming.
