Using this Basil Bloom Field double pannier bag is a breeze. First, decide how you want to attach it to your bike carrier. You can use the pre - mounted straps with the Universal Bridge system. If you have the Basil DBS system or MIK adapter plates (which you need to buy separately), you can use them for attachment too. When you have heavier items in the bag, don't forget to add the Basil Distance Holder (sold separately) to avoid any issues with the bike spokes. As for maintenance, simply wipe the bag with a damp cloth if it gets dirty. Make sure to keep the zippers and Velcro clean to ensure they work smoothly. Also, if it's wet, let it dry thoroughly before storing it. Remember, the bag is waterproof, but try not to submerge it in water for long periods to maintain its waterproof quality.
