The ultimate modular storage solution for the organized carper. At Gerry’s Fishing, we know that keeping your gear dry and easily accessible is the difference between a smooth session and a chaotic one. The Nash Subterfuge Waterbox Pouch XXL is the largest in the range, offering a massive 5.7L capacity designed to bring total waterproof protection and rigid structure to your luggage system.
Unlike traditional fabric pouches that collapse and soak up moisture, the Waterbox Pouch is engineered from reinforced moulded EVA. It functions more like a solid storage box, protecting your expensive tech, spare clothing, or bulk tackle from being crushed or getting wet. With its stackable square profile, it integrates seamlessly into the Subterfuge Waterbox Carryalls, allowing you to build a custom, modular kit tailored to your session.

The XXL size is the “Big Brother” of the pouch family, perfect for bulkier items:
Tech & Power: The rigid EVA construction makes this the ideal home for large power banks, DSLR cameras, and tablet devices that need protection from both impact and dampness.
Clothing & Accessories: Perfect for storing a spare dry base layer, a winter hat and gloves, or a compact towel to ensure they remain bone-dry until needed.
Bulk Tackle Storage: Ideal for carrying large amounts of lead, PVA refills, or multiple tackle boxes that you want to keep organized in one stackable unit.
Bait & Pop-Ups: Great for holding several tubs of hookbaits or a large selection of baiting tools and liquids.
Pro Tip: The translucent lid is a game-changer for high-pressure sessions. You can instantly identify the contents without having to unzip multiple bags. Use the internal mesh pocket under the lid for smaller essentials like charging cables, needles, or licensing documents to keep them separate from the main compartment.
Is it actually 100% waterproof?
The EVA material and heat-welded seams are fully waterproof. While the zips are high-quality matte waterproof zips designed to handle persistent rain and wet grass, the pouch should not be fully submerged for extended periods. However, for standard bankside use, your gear will remain perfectly dry.
Can these be stacked on top of each other?
Yes. The Waterbox Pouches are designed with a low-profile, flat-top shape specifically so they can be stacked inside larger carryalls or rucksacks. This “modular” design prevents them from sliding around or collapsing under weight.
Are the corners reinforced?
The entire unit is made from moulded EVA, which naturally holds its shape. The corners are rounded internally to make it easier to retrieve small items that might otherwise get stuck in a sharp crease.
How do I clean it?
Because it is EVA, it’s incredibly low maintenance. If it gets covered in mud or spod mix, simply wipe it down with a damp cloth or rinse it under a tap. It won’t absorb smells or stains like traditional nylon bags
