Modular hitch-mounted exoskeleton for adventure Decades of product design, on-the-road testing and pure adventure have led us to revolutionize the humble trailer hitch with a system we’re calling EXO. It’s much more than a singular product. It’s an entire system that pushes the hitch to its full potential as a do-anything, go-anywhere multi-tool. Whether hitting the singletrack, the slopes or a favorite unnamed spot on the map, EXO can answer every need with a full range of accessories, allowing the hitch to store anything needed for virtually any adventure.
