45 Litre Waterproof Duffel / Backpack

A Truly Waterproof Duffel That Does Not Need a Roll-Top

Most "waterproof" bags rely on a roll-top closure that is fiddly to seal and easy to get wrong. This 45-litre duffel uses an airtight zipper and ultrasonically welded seams to keep water out completely — rain, river crossings, boat spray, or a downpour at camp. Carry it as a backpack, shoulder bag, or grab-handle duffel depending on the situation.

Key Features

• Fully Waterproof Airtight Zipper: No roll-top required. Zip it shut and your gear stays dry — simple as that.
• Ultrasonic Welded Seams: Every seam is heat-welded rather than stitched, eliminating needle holes where water can seep through.
• 500D PVC Exterior: Heavy-duty waterproof fabric that handles abrasion, UV, and rough treatment on the trail.
• 3-Way Carry System: Adjustable straps let you wear it as a backpack, sling it as a shoulder bag, or carry it by the reinforced grab handles.
• Air Bleeder Valve: Open the valve after loading to compress excess air out, making the bag more compact for packing. Close it to add air for buoyancy on the water.
• Multiple Tie-Down Points: Secure it to a roof rack, motorbike, kayak, or trailer with ease.
• Water-Resistant External Pocket: Quick-access pocket on the outside for items you need without opening the main compartment.
• Silicone Grease Included: Zipper lubricant provided for long-term maintenance and smooth operation.

Built For

• 4x4 and Overlanding: Strap it to your roof rack or throw it in the tray. Your clothes and gear stay dry through river crossings and dust storms.
• Kayaking and Boating: Airtight construction doubles as a dry bag on the water. Use the air valve for added flotation.
• Camping and Hiking: Backpack straps make it easy to carry from the vehicle to camp. Keeps bedding and clothes dry in any weather.
• Motorbike Touring: Tie-down points on the base make it easy to secure to a pillion rack or panniers.
• Travel and Checked Luggage: Tough enough to handle airline baggage handling while keeping contents protected from rain on the tarmac.
