The RotopaX Pack Mount gives you a simple way to attach RotopaX fuel, water, or storage containers to any flat surface on your Subaru, whether that's a roof rack, bumper, or RackWing-style external mount. Installation is a twist-and-lock design: set the container on the mount and turn it to tighten, no tools or extra hardware needed. It holds securely enough to handle washboard roads and rough trail sections without the container working loose. A practical way to add fuel or water capacity for longer trips without using interior cargo space. We ship this from our Calgary shop across Canada.
