Fishpond Thunderhead HD Backpack

Built for long approaches, deep crossings, and demanding days in the backcountry, the Fishpond Thunderhead HD Backpack provides fully submersible storage for a full day's fishing gear.

Its large clamshell opening makes packing and accessing equipment straightforward, while the spacious main compartment leaves plenty of room for extra layers, food, and other essentials. Exterior attachment points provide convenient storage for rods, nets, and frequently used accessories without taking up valuable space inside.

Constructed from TPU-laminated, 100% recycled 1000D high-tenacity polyester ripstop, the Thunderhead HD is designed to protect your gear in challenging conditions. A waterproof TIZIP® main closure keeps the compartment fully submersible, while an exterior quick-access pocket with TRU® Zip closure offers convenient storage for smaller items. A molded back panel with integrated net passthroughs, adjustable sternum strap, and removable lumbar strap help keep the pack comfortable and secure over longer distances. Interior mesh organization and a removable floating pocket make it easier to keep essential items organized and accessible.

Q: What are fly fishing backpacks used for?
A: Fly fishing backpacks are designed to carry your essential gear for longer days on the water or multi-day adventures. They offer ample space for fly boxes, extra layers, food, hydration, and accessories while keeping your gear organized and easily accessible.

Q: What makes a fly fishing backpack different from a regular backpack?
A: Fly fishing backpacks are purpose-built with water-resistant materials, tool attachment points, and internal organization tailored to anglers. Many feature net holsters, retractor mounts, and waterproof compartments to protect valuable gear in wet environments.

Q: Are fly fishing backpacks waterproof?
A: Many are water-resistant, while select models are fully waterproof with welded seams and submersible zippers. Waterproof backpacks are ideal for boat fishing, heavy rain, or deep wading — while water-resistant packs balance protection with comfort and breathability.

Q: How do I choose the right fly fishing backpack?

Q: How should I care for my fly fishing backpack?
A: Rinse your backpack with fresh water after use, especially if exposed to salt or mud. Allow it to dry completely before storage and occasionally lubricate zippers or buckles on waterproof models to maintain performance.
