The Marathon 8.8mm Half has the sheath durability of a single rope, a performance enhancing dry core and sheath, and is recommended for multi-pitch, trad or wandering routes and especially for alpine use where water absorbtion reduces the working specs of non dry ropes.

There is always something thinner, not always lighter. If you're concerned about value then our advice is to go thicker with the rope diameter: more sheath = longer rope life.
