Technical info:
Zag is designed in Chamonix and features the characteristic block letter design. Ubac is marketed as Zag´s most versatile ski touring model. This light ski has a long rocker and soft flex in the front and a little more sidecut at the waist than at the tip. The camber is the highest in the test (8 mm), with fairly long setback (16 cm) and no taper in the tail.

On snow:
Ubac is first and foremost a ski that turns well in moderate terrain, provided that the speed isn’t too high. It is light, the edge grip is decent and it carves well on snow that isn’t too difficult to handle. We miss more flexibility and response at high speed. The light construction, together with the relative powerful camber and the pronounced sidecut, gives a somewhat crisp and stiff feeling. Zag Ubac is a good choice if you want a light and wide ski, and if you prefer long trips and many vertical metres to short ascents/descents.
