The OverBoard 5 litre Blue dry tube bag is built to last and protects small valuables or clothes wherever water, dirt or sand is involved. Made of nylon-coated PVC tarpaulin, this Dry Sack is also super durable and easy to wipe clean, meaning it can take a bit of a beating. A fully adjustable and removable strap means you can carry this bag hands-free while loading your craft or bringing your stuff to the beach.
