Thunderstorms, rain forests, and waves are no match for our Fishpond Thunderhead Submersible 100L Duffel. This sturdy duffel features a 900-denier fabric that's made from recycled plastic bottles and coated with polyurethane for serious abrasion resistance and water resistance. In fact, it's fully waterproof and submersible, thanks to its self-healing, waterproof zipper. The Thunderhead features a humungous 100-liter capacity for those of us who pack extra gear, layers, and tackle, and it easily carries two fly rod tubes with its external straps and another 4-piece fly rod tube on the inside. This duffel features climbing rope handles as well as tuck-away backpack straps that we can whip out if we need to chuck the pack on our back to free our arms to carry a cooler, load of dry bags, or stringer of fish back to our cabin, campsite, or lodge.
