Manufacturer Description: Updated for the 2019-20 season. At 118mm underfoot, this is a lightweight, big-mountain backcountry ski made for the deep days that also feels responsive in the crud and harder conditions. It floats, drifts, and sails through the fluffy stuff while strong construction materials promise that the CT 4.0 can handle tree taps, deep landings, and gnarly freeride faces with ease.
