The Big River Dry Bag by Sea to Summit is the bag for the kayak cabin and the sack for the hike pack!
With lash loops for latching to bike forks, kayaks, and 4WD racks – this bag boasts flexible, waterproof, and rugged durability during any water-based activity, while still light enough for the lowkey trips. An oval shape allows a snug fit into any storage space, encouraged too by the non-wicking roll-top closure for a naturally rounded top, ultimate tackle security, and moisture management. The oval base is triple coated too, ensuring increased water shedding and robustness against abrasion.
This dry bag is of a 420D Nylon construction with a TPU coating that boasts a 10,000mm Hydrostatic Head (HH). The HH is a measure of water resistance – and in this case specifically, the water pressure the bag can withstand before submitting to leakage. The interior white PU-coating allows a reflective panel for easy identification in low light conditions, from after dark touring to tightly packed kayaks.
From the rapids to footpaths, and bike tracks to roof racks – the Sea to Summit Big River Dry Bag offers peace of mind and reliable protection.
