The right athletic jacket can help to keep you warm while allowing the skin to breathe. Athletic jackets are available in a wide variety of materials including cotton, spandex and polyester blends.These jackets also are available in many different styles, colors and prints. When looking for an athletic jacket think about when you will most often wear it. If it is for running outdoors during the colder months you may want to choose a thicker, heavier material to provide greater warmth. If you are looking for an athletic jacket that will carry you through the warmer months, opt for a more lightweight and breathable material that can shield you from the elements while keeping you cool. Athletic jackets are best if they fit somewhat close to the body and do not have many zippers or pockets that make the jacket more bulky. Look for stretch blends so that the jacket can allow for flexibility and mobility. Athletic jackets are available at many different price points, but for a quality jacket $80 is a reasonable price. Great athletic jackets can be found at Lululemon and Under Armour.
