Testimonials

  • Fits under the carport perfectly

    "I needed extra roof storage but couldn't afford to add much height. The ultra-low profile of the 48L case means I can still clear my carport at home. It’s surprisingly quiet on the highway at 100km/h too—no whistling. The quick-release plate took a few minutes to dial in initially, but once set, it’s rock solid."

  • Kept the bull dust out

    "Took the 92L case up the Oodnadatta Track. The PP alloy handled the constant corrugations without cracking. More importantly, when we hit a creek crossing, the IP67 seal did exactly what it claimed. Our recovery gear and clothes stayed completely dry and free of red dust. The built-in locks are a great touch so I don't have to fiddle with rusty padlocks."

  • Practical for weekend trips

    "I use my rig for work during the week, so I don't want a massive box permanently fixed to the roof. The stainless steel vise-grip system makes it genuinely straightforward to mount the 76L case on Friday afternoons and take it off Sunday night. Holds my wet swags and camping chairs perfectly."

  • Secure storage for expensive gear

    "Switched from soft roof bags to the 58L hard case. The dual combination locks mean I can leave my rig parked at the local roadhouse without stressing about my air compressor and tools walking away. I've even stood on it to reach the far side of my rack, and the lid didn't flex—that 100kg load rating is accurate."

  • Solid build, does what it says

    "The material feels incredibly rigid and hasn't faded or warped after a solid month in the WA summer sun. Setting up the combination lock was slightly finicky on the first try, but the latches clamp down hard and pull the weather seal tight. A very functional and durable piece of kit for touring."
