Ski suits are generally divided into sportswear and travelwear. Competitive clothing is designed according to the characteristics of the competition, focusing on the improvement of sports performance. Tourist clothing is mainly warm, beautiful, comfortable and practical. The color of the ski suit is generally very bright, which is not only aesthetically pleasing, but also more important in terms of safety. If skiing in the mountains, especially on steep hillsides, away from the construction of the skiing site is prone to collapse or disorientation, in this case bright clothing provides a good vision for the search.
