Best waterproof/resistant tackle bag/box for my kayak.

As the topic stated , looking to grab something from the 15% from tackle warehouse sale. I use a black pack from yak attack for my kayak but I need something else to hold the rest. soft plastics , pliers , fish grippers and to be able to hold plenty of Plano boxes.  My current one gets wet on the bottom and soaks threw on long days in the water. Looking for something more secure. I have a frontiers 12 so it has plenty of space for a decent.  sized bag behind me.
