When you intend to go out to run, your clothes are very important to consider. Wearing special running shirts is a must. Running shirts are made of special materials that insure complete comfort, durability, dryness, water resistance, wind resistant and ease of sweat evaporation. Running shirts must also be light weight, they cannot hinder you movement or speed or annoy you body while moving. Running shirts are made of different materials like nylon, polyester, jersey, cotton or different quick dry fabrics. Running shirts can be plain with no pockets or zips, while others can have a quarter zip for extra space for the neck. Running shirts can have short sleeves for hot weathers and more free feeling, or can have long sleeves for slightly colder weathers. They are available in many different colors, and can be size fitting or looser. Some running shirts can have moisture wicking fleece layer to give warmth and dryness while running, while having smooth outer layers.
