Hulk4x4 Hydro Bag Range – Waterproof Adventure Bags

Gear up for any off-road adventure with the Hulk4x4 Hydro Bag Range, engineered to keep your equipment protected, organised, and ready for action. Available in 40L, 60L, and 90L, these heavy-duty waterproof bags are built for 4WD touring, camping, boating, fishing, and all outdoor exploration.

Unmatched Protection Against the Elements

Designed for harsh Australian conditions, every Hydro Bag is constructed from tough 500D PVC waterproof material and fitted with IPX7 air-tight zippers. This creates an impenetrable barrier against water, dust, mud, and sand—ideal for creek crossings, beach driving, and wet-weather touring.
The air-tight design maintains positive internal pressure, ensuring your clothing, electronics, and essentials stay completely dry and safe. With the HULK Hydro Bag Range, you can explore with confidence in any weather.

Smart, Practical Design for Off-Road Use

Built with real-world adventure in mind, the Hydro Bags feature:

• Accessible side pockets for essentials
• Heavy-duty “D” buckles positioned on all sides for secure tie-downs
• Integrated pressure valve for altitude or air-pressure adjustments
• High-frequency voltage-sealed waterproof seams for total protection

These features make the Hydro Bag a dependable companion whether it’s strapped to a roof rack, mounted in the tub, or carried through the campsite.

Carry Comfortably – Anywhere

The 40L and 60L Hydro Bags include detachable padded backpack straps, allowing for hands-free transport when loading gear or hiking to your campsite. Multiple reinforced carry handles offer easy handling from any angle—perfect for quick packing and unloading on the tracks.
