Sea to Summit Big River Dry Bag 8L – Waterproof 420D TPU Drybag, Hypalon Roll-Top, Green

Sea to Summit Big River Dry Bag 8L – rugged waterproof storage for real adventures

The Sea to Summit Big River Dry Bag (8L) is built for harsh conditions: abrasion-resistant 420D ripstop nylon laminated with TPU for strength and waterproofness. Perfect for kayak/canoe, bikepacking, fishing and travel.

• 10,000 mm waterproof rating (fabric) – great for rain and spray
• Oval base helps prevent rolling
• Hypalon roll-top closure + reinforced seams for long-term durability
• Lash points for secure mounting on bikes, kayaks and luggage racks
• Packs small when empty, stays stable when loaded

Note: The body fabric is highly waterproof (10,000 mm), but as with any roll-top dry bag, avoid prolonged submersion. For best protection, roll the top 3–4 times.
