Using your 32L Dolphin pannier pair is easy. First, open the front pocket made of elastic material to store personal items like keys or small notebooks. The wider and stretchy side pockets are great for water bottles or other items of various sizes. When packing, use the side attachment webbing straps. You can choose to pass them inside or outside the pockets to compress and secure your load. Also, don't forget to pass the webbing strap under the light tabs if you have lights attached. As for maintenance, after each use, wipe the panniers with a damp cloth to keep them clean. If they get wet, let them dry thoroughly before storing. Avoid sharp objects that could tear the material. With proper care, your Dolphin panniers will serve you well on many cycling trips.
