Using your Acepac Saddle Harness MkIII is easy. First, attach the harness to your saddle using the clamping system. If you're using it with a Saddle Drybag, simply place the drybag in the harness. It can also be used with other bags or packs, so get creative! When it comes to maintenance, keep it clean by wiping it down with a damp cloth. Avoid using harsh chemicals as they may damage the Nylon Robic material. Also, store it in a dry place when not in use to prevent mold and mildew. Remember, the Saddle Drybag is sold separately, so make sure to purchase one if you need it. With proper care, your harness will last you a long time and serve you well on your adventures.
