In this theoretical thesis, the competition discipline of giant slalom is presented, from its inception to today.

In order for skiers to enter the competition, they are required to use equipment prescribed by the FIS (World Ski Federation). Therefore, all the necessary ski equipment is described, while skis are the most technologically demanding, and functionally the most important part of the equipment are described in detail from the beginning to the development of modern carving skis.
