With a larger tread area, Trax total-terrain contouring allows for the most complete traction for your self-recovery scenarios. Comprised of recycled rubber, the design is based on the hard gripping, continuous track of tank and rover vehicles. Individual, double-sided articulated tread sections allow Trax to conform to the ground – be it rut, hole or steep, slick & uneven terrain – and immediately provide bite for your tires (with no spin-out!) while gripping the terrain. Once you’ve recovered, the Trax rolls up compactly and easily stows away so there’s no need for mounting! At 20lbs, Trax is heavy-duty enough to get the job done and light enough not to slow you or your adventuring down!
