Well-ventilated waterproof jackets are used most often by skiers to keep them warm and dry from the elements while also dissipating extra heat when working the slopes.
Some ski jackets come with hoods or remove bale hoods to add warmth to the jacket. One disadvantage to having a hood is that it blocks peripheral vision.
Some ski jackets have powder skirts. Located at the waist and approximately 2 inches long, the powder skirt snaps closed and cinches down the waist to keep snow out. Cinch cords also serve a similar purpose.
Sometimes referred to as body mapping, ski jackets are being designed with longer bent arms and with longer fits in back to fit the movement of skiers.
Seemed zipper seals, ski pass pockets, iPod headphone threading holes and even jackets equipped with a Recco avalanche protection system are just some of the extras you may find on a ski jacket.
