The Yeti’s Panga Backpack 28 is your best choice after the Duffel bag. It’s a durable bag that is also waterproof. Next time you are out camping or fishing, it will keep your phones and other gadgets nice and dry. In addition to that, since it is airtight, you can use it as a floatation device if you lose your footing in the water. It has clasps that wrap around the chest and your waist to keep it stable when you are hiking too. The Velcro back pad will also help you carry optional accessories.
