Attwood Marine Heavy-Duty Dry Bag, 500 Denier PVC, Roll-Top Closure

Overview

The Attwood Marine Heavy-Duty Dry Bag is a waterproof storage bag range for keeping gear protected on boats, kayaks, canoes, and around the dock. It is available in 20 liter and 40 liter sizes, with the 20 liter version holding about 5.28 gallons and the 40 liter version holding about 10.57 gallons.

The bag uses 500 denier PVC coated mesh fabric with safety yellow coloring and black accent components, making it easier to spot on deck, in a cockpit locker, or near other safety gear. It is a practical option for clothing, towels, boat papers inside a separate pouch, small tools, electronics in their own cases, and other items that need extra protection from spray, rain, and wet decks.

Key features

• Waterproof construction helps protect contents from spray, rain, and wet storage areas on board.
• 500 denier PVC coated mesh fabric gives the bag a tougher feel than lightweight day-use sacks.
• Safety yellow color helps the bag stand out in a locker, dinghy, kayak, or cockpit.
• Multiple D-rings give attachment points for waterproof cases, dry boxes, and other small essentials.
• Soft touch integrated carry handle makes the bag easier to grab when loading gear or moving around the boat.
• 1-1/2 inch adjustable shoulder strap supports easier carrying between the dock, car, and vessel.

Variants

This dry bag is offered in two capacity configurations for different storage needs on board.

The size is the key difference between the variants. The waterproof construction, 500 denier PVC coated mesh fabric, safety yellow and black color scheme, multiple D-rings, integrated carry handle, and adjustable shoulder strap are consistent across the range.

• 11894-2: Size 40 Liter. This larger capacity suits bulkier gear such as spare clothing, towels, rain layers, or items grouped for a day on the water.
• 11897-2: Size 20 Liter. This smaller capacity is easier to stow in tight spaces and works well for personal gear, compact safety items, or essentials kept close at hand.

Use on board

This bag makes sense for boaters who want portable dry storage without adding a fixed locker or hard case. It can ride in a cockpit, under a console, inside a cuddy, in a dinghy, or in a kayak where spray and wet floors are part of the trip.

For electronics, documents, and other sensitive items, use an additional waterproof pouch or case inside the bag when extra protection is needed. As with any dry bag, the closure should be rolled and secured correctly before exposure to wet conditions.

Care and storage

After use in saltwater areas, rinse the outside with fresh water and let the bag dry before long-term storage. Keep sharp tools, hooks, and abrasive hardware from rubbing directly against the fabric so the waterproof barrier stays in good condition.
