What Our Gearhead(R) Experts Are Saying: "I've hauled this duffel through airports, river put-ins, and rainy trailheads, and it just won't quit. The fully submersible main compartment gives serious peace of mind when you're around water, and the size is perfect for multi-day trips where you need to bring everything. The climbing-rope handles are super comfortable for heavy loads, and the stowable backpack straps make hauling really easy when the gear pile gets big."We trust the Thunderhead Grande Submersible Duffel when the adventure calls for rugged protection and massive hauling power. Built for wet boat decks, alpine storms, and gear-heavy expeditions, this 100-liter duffel shields our equipment behind a fully waterproof main compartment that stands up to driving rain, crashing waves, and rough travel days. Whether we're loading up for a week on the river or preparing for an overland escape, the burly NewStream fabric and submersible closure give us the confidence to bring sensitive gear without worrying about the weather. Carrying big loads is surprisingly easy thanks to stowable backpack straps and climbing-rope handles that stay comfortable even when the bag is packed to the brim. Exterior lash points and daisy chains let us secure rod tubes, tie down extra layers, or attach gear on the fly. Inside, the generous layout offers room for waders, boots, layers, and travel essentials, with sizing that fits 9ft, 4-piece rod tubes for fishing-focused missions. From international travel to long river floats, the Thunderhead Grande delivers expedition-worthy durability with the waterproof reliability we need in unpredictable environments.
