Using your Basil Ever - Green double bicycle pannier bag is easy. First, decide how you want to attach it to the carrier. You can use the pre - mounted straps for a fixed attachment, or if you prefer a removable option, buy the Basil DBS system or an adapter plate like MIK separately. Once attached, you're ready to start packing. You can adjust the water - resistant folding clasp with the carabiner hook to increase the bag's capacity when you have more items to carry. The front pocket with a magnetic closure is great for quickly accessing small things. If you're carrying heavy items, consider adding the Basil Distance holder (sold separately) to keep the bag away from the bike spokes. When it comes to maintenance, since the fabric is water - repellent, a simple wipe with a damp cloth should be enough to clean it. Store the bag in a dry place when not in use to keep it in good condition. Also, be careful not to over - load the bag beyond its 32 - litre capacity to avoid any damage.
