A dependable, waterproof dry bag is a must-have for boat life. This is our most spacious and sturdy dry bag to keep your essentials safe in bad weather and rough seas. The Ocean dry bag has extra-strong 420D nylon with waterproof TPU backing. We reinforced the watertight properties by using highly durable and leak-proof radio-frequency welded seams. It closes with a secure roll-top and buckle. A removable shoulder strap makes it easy to carry when loading and unloading the boat. Although designed for water sports, this dry bag is useful anytime you need extra protection from the elements. Roll-top dry bags do not provide waterproof protection if completely submerged.
