The Stormfront 25L Backpack from Patagonia is an ultra-simple, waterproof fishing pack that features a PU exterior coating, a single-side, TPU-coated nylon interior and a fully waterproof TIZIP main zipper. The Stormfront is comfortably supported by a removable shoulder-strap harness with 3D spacer mesh for increased air circulation.
Take the harness off and you have the perfect fishing bag for wet boat decks. There's also an external, water-resistant stash pocket, while inside, the glued-in zippered mesh pocket keeps valuables organized. The harness system includes tool attachment and storage capabilities.
