Using this Condor utility shoulder bag is a breeze. Unzip the main compartment to put in your stuff, and use the three internal pockets to sort items like keys, cards, or pens. You can attach extra pouches or tools to the modular attachment straps and heavy - duty webbing according to your needs. When you don't want to use the shoulder strap, just remove it. To keep the bag in good shape, avoid overloading it as it may damage the zippers or straps. Wipe it clean with a damp cloth regularly. Don't machine - wash it, as this could harm the bag's structure. Store it in a dry place when not in use.
