In a nutshell, windproof jackets can be divided into three broad categories—wind breakers, rain jackets and hardshell jackets. The lightest of the three, wind breakers are just thin outer shell garments usually made of breathable nylon or some similar lightweight material. Their construction allows them to be lighter, less expensive and more breathable than the other jackets in this category. When not in use, they can be rolled up into a small, neat bundle and tucked away until they are needed again. Rain jackets, as you would expect, are made to keep you dry, but can keep the wind from mercilessly punishing you whether it is wet or dry out. They’re typically made of waterproof, breathable fabrics that not only keep water from coming in, but wick moisture away from your skin to keep you drier. Hardshell jackets are the heaviest and warmest of the three types, and also generally the most expensive. These insulated jackets are constructed of three layers—a strong face fabric, a waterproof/breathable membrane and an insulating layer closest to your body.
