Nothing is more uncomfortable during workouts and sports than a tee shirt sodden with sweat. The best way to combat this is with athletic t-shirts made of a moisture-wicking fabric. The material pulls moisture away from the skin to the outside of the fabric, where it can evaporate easily. Even in cold weather, your body can overheat if perspiration stays on the skin, so wicking tees are good for layering as well.
There's no need to sacrifice style for comfort either. Wicking tees range from slim-fit short sleeve tees to polo shirts, long sleeved tees and turtlenecks. Some brands, like Under Armour, specialize in high performance clothing, with cold-blocking and moisture-wicking properties, 4-way stretch, odor-stopping and soft brushed material. Some wicking tees are constructed with compression as well, to support muscles and minimize muscle fatigue. Whether your outing is a round of golf or an Iron Man event, you'll play better and feel better in a tee shirt that helps regulate body temperature and keeps you dry.
