Between winters spent chasing wild steelhead in the Pacific Northwest and summers exploring the angler mecca known as Alaska, the Orvis Waterproof 21L Backpack will haul all the necessary tackle you need for your more adventurous fishing trips while keeping it all dry when you venture into notoriously rainy parts of the world. Orvis made this pack from a hard-wearing 500D nylon coated with a TPU laminate to protect the internal compartment from heavy rain and the occasional dunk in the river. Flexseal YKK zipper act as a water-tight seal to both the front pocket and main compartment, but they aren't completely waterproof so you won't want submerse the bag for too long if you're carrying water-sensitive electronics.
