Step-by-Step Guide:
- Clean and dry your truck bed surface.
- Unfold your cargo bag and position it centrally in the bed.
- Pack your items evenly, heavier items on the bottom.
- Close the bag fully, ensuring all zippers and overlaps are secure.
- Use the provided straps to anchor the bag to bed rings, rails, or tie-down points. Tighten evenly.
- Double-check that the bag is taut and doesn’t shift.
- For added safety, periodically stop and recheck the bag during long trips.
Maintenance and Care Tips
Waterproof truck bed cargo bags are engineered for durability, but regular maintenance increases their lifespan:
- After Each Use: Remove the bag, empty, and shake out debris. Wipe with a damp, soapy cloth and air dry completely before storing.
- Inspect for Wear: Check seams, zippers, and mounting points for damage. Address early signs of wear to prevent leaks.
- UV Protection: If possible, store your bag away from prolonged sunlight exposure to prevent material degradation.
- Store Properly: Fold and store in a cool, dry place. Many bags include a storage pouch for convenience.

- Lockable Zippers: Many premium models come with lock-ready zipper pulls for added security.

What is a waterproof truck bed cargo bag?

How do I know what size cargo bag fits my truck bed?
Measure your truck bed’s length, width, and height, then compare it to the bag’s dimensions and capacity. Choose a bag slightly smaller than your bed for easy fitting and strap attachment.
Can I use a cargo bag without a tonneau cover?
Yes, waterproof cargo bags are designed for uncovered beds. Their materials and sealed seams ensure weather protection even when fully exposed.
Are these bags theft-proof?
While many bags have lockable zippers, soft bags are not entirely theft-proof. For enhanced security, use bed locks, cable locks, or store the bag out of sight when possible.
Will the bag scratch my truck bed?
Most quality bags feature soft undersides or include anti-slip mats to minimize the risk of scuffing your paint. Ensure your bed is clean before installation to avoid trapped debris.
How do I store the bag when not in use?

Can the bag withstand highway speeds?
Yes, when properly secured using tie-down straps and bed anchors, modern waterproof cargo bags are tested to stay in place at highway speeds.
Is a cargo bag better than a hard tonneau cover?
