Fidlock magnetic self-sealing dry bags are a game-changer in the world of waterproof bags. The slick magnetic closure snaps itself shut and immediately seals out 100% of moisture and sand, keeping valuables like phones and keys safe while you are out on the river or in the backcountry. The clear plastic on the front even allows for using the touchscreen on your phone while still in the bag, so you don't have to risk getting it wet when you need to use it.
