Dynafit is offering a wide range of ski and speed touring skis of all sizes and weights. The Cho Oyu is – in my opinion – the ski that fits “wide and light” best. I recently purchased an Cho Oyu and I am quite happy with it. The ski is fairly wide (125 – 88 – 111) and is at the same time quite light (1190g per ski at 174cm). The Cho Oyu is easy to in most conditions. Edge grip is not great and it certainly not a carving ski for groomed slopes. The Cho Oyu likes moderate speeds.
In summary, a good and light ski with moderate waist (88mm). Easy to ski. One should note, however, that Dynafit skis are usually a bit more expensive than skis of other brands.
