Using your JR Gear Compression Dry Bag is easy. First, open the magnetic closure and put your items inside. Try to pack them tightly so you can use the compression straps to reduce the bag's size. Make sure the magnetic closure is properly sealed to keep water out. When using it, avoid sharp objects that could tear the bag. After use, if the bag gets wet, dry it thoroughly before storing. Store it in a cool, dry place to maintain its quality. If there are any stains, you can gently clean the bag with mild soap and water.
