There is no right or wrong answer to this question – it depends on personal preference and the weather conditions you typically ski in. Some people prefer thicker jackets for extra warmth, while others find them to be too bulky and prefer thinner jackets that offer more mobility. Ultimately, it is up to the skier to decide what type of jacket works best for them. If you typically ski in cold weather conditions, a thick ski jacket may be a good option for you. These jackets will provide extra insulation to keep you warm on the slopes. However, they can also be quite bulky and may limit your range of motion. If you plan on doing any tricks or flips while skiing, a thinner jacket may be a better option.
