Roof Boxes vs Roof Bags: What’s Right for You?

Need more space for your next trip? Whether you're packing for a holiday, a family road trip, or a weekend escape, roof storage is a game changer. But what should you go for — a solid roof box or a flexible roof bag?

Let’s break down the pros, cons, and which option suits your setup best.


📦 What Are Roof Boxes?

Roof boxes are hard-shell storage containers that mount securely to your roof bars. They’re built to be aerodynamic, weatherproof, and secure.

✔ Pros:

  • Fully waterproof

  • Aerodynamic for better fuel economy

  • Secure locking systems

  • Long lifespan

❌ Cons:

  • Bulkier and heavier

  • Requires storage space when not in use

  • More expensive

🛒 Ideal for: Families, frequent travellers, gear-heavy holidays

🧳 What Are Roof Bags?

Roof bags are soft-sided, foldable carriers made of weather-resistant materials. They’re lightweight and flexible, and can be stored in your boot when not in use.

✔ Pros:

  • Lightweight and compact

  • Folds down when not in use

  • Lower cost than roof boxes

  • Easier to store

❌ Cons:

  • Less secure (some don’t lock)

  • Water resistance varies

  • Not ideal for very long or harsh-weather trips

🛒 Ideal for: Occasional trips, city breaks, extra luggage
