HeatgearŪ for when it's hot. Keeping athletes cool, dry and light. The original "second skin" layer that sparked the revolution of performance apparel. HeatgearŪ is engineered with the Under ArmourŪ Fabric, a microfiber blend featuring their signature Moisture Transport System and reliable compression. It's designed to fit tight to your skin. HeatGearŪ slides over your body with a second-skin fit, delivering compression without restriction, making it the perfect choice for any activity, on the field or on the job. The UnderArmour fabric pulls perspiration off your skin, leaving the moisture on the outside of the shirt where it runs off or evaporates. The result? You're left cool, dry, and lighter than the competition.
