The most popular ski jacket materials are synthetic, wool and cotton. Each of these materials is highly popular among a specific type of skier, and each material also has its drawbacks and advantages. Synthetic jackets (made from acrylic, nylon and polyester) are lightweight, weather-resistant and inexpensive, but they lack the warmth of other materials. Wool is warm, cozy and can breathe, and many people like the way wool looks and feels.  Cotton has the same pros and cons of wool, but it is less expensive and takes longer to dry, because cotton traps and holds moisture. There are many other types of fabrics and materials used in ski jackets, and each has its advantages and disadvantages. The best way to pick a ski jacket is to find a material that keeps you comfortable throughout the ski day, while also fitting your style and keeping you fashionable!
