From the confines of our favorite local fishing hole to the remote open spaces of Montana, Idaho, and Washington, the Fishpond Thunderhead Submersible Backpack protects our necessities all along the way. The Thunderhead features a highly durable and waterproof TPU-coated NewStream construction that works in tandem with a TIZIP closure for a secure seal we can depend on if we take a dip. We really appreciate that the shoulder harness system adjusts vertically for a personalized fit and feel, while the removable hipbelt adds even more versatility. Plus, multiple Hypalon attachment points and a variety of organizational spots keep our fly boxes, tackle, and tools within reach when we're on the river.
