The Thunderhead Submersible Sling impresses from the get-go with its seamless fusion of design and durability. Crafted from a highly durable nylon, this sling isn’t just a bag; it’s a fortress against wear, tear, and the unpredictability of the great outdoors. The attention to detail is evident, from the robust TIZIP waterproof zipper to the reinforced corners that defy the harshest elements.

Submersible Excellence: Keeping It Dry Below the Surface

The standout feature of this sling is its submersible capability. No more fretting about sudden downpours or accidental dunks; the Thunderhead Submersible Sling laughs in the face of water. The TPU welded fabric and the TIZIP zipper create a watertight seal, ensuring your gear stays dry even when the unexpected happens. It’s a game-changer for those who embrace the water’s edge with open arms.

A Symphony of Space and Organization

Ample Storage: Room for Every Essential

Step into the spacious realm of the Thunderhead Submersible Sling, where every nook and cranny is optimized for functionality. With a 13L capacity, this sling strikes the perfect balance between compactness and roominess. It accommodates your fly boxes, reels, spare clothing, and even a hydration system—a true companion for extended fishing escapades. All this space comes at only 1.8lbs which means you can pack a lot of stuff into the Thunderhead without feeling the weight on your shoulders. In case you do, there’s an additional strap at waist high to distribute the weight further.

Organization Nirvana: Pockets with Purpose

Organization is an art, and Fishpond has mastered it. The array of purpose-built pockets ensures that everything has its place. From a large main compartment to stash your essentials to smaller pockets tailored for tippet spools, leaders, and tools, every detail speaks to the angler’s need for order in the midst of action. What I like in particular is the zippered outside pocket for quick access to essential. Be aware though that although this pocket is highly water resistant it’s not fully waterproof.

Wearing Comfort: A Sling That Adapts to You

Sling Dynamics: The Freedom to Move

Wearing comfort is non-negotiable, especially when navigating challenging terrains. The Thunderhead Submersible Sling doesn’t just sit on your shoulder; it becomes an extension of your movement. The single shoulder strap allows for quick swings to the front, providing instant access to your gear without the need to take off the sling. It’s a dynamic design that caters to the angler on the move.

Two other cool features are the integrated net slot that allows you to safely tuck in your landing net if you’re wade fishing a river for example. And the rod tube holders allow for the attachment of a tube if you want to bring an extra rod.

Weather wading through rivers, hiking along overgrown trails, or facing unexpected rain showers, this sling stood resilient. The waterproof zipper performed flawlessly, and the ergonomic design allowed me to move freely without hindrance.

Versatility Unleashed: Beyond Fly Fishing

What sets this sling apart is its versatility. While it’s a stellar choice for fly fishing, its design makes it a reliable companion for various outdoor activities. Whether you’re a photographer capturing the perfect shot in wet conditions or a hiker navigating through diverse landscapes, the Thunderhead Submersible Sling adapts to your needs.
