Our base layer form fit shirts conform to the body’s contours. Unlike other form fit and compression shirts on the market, our 3D XOSKIN™ form fit base layers stretch approximately 4 inches in order to conform to your body without the use of any Spandex® or Lycra®. These synthetic fibers, which are found in most compression products, add weight to a garment. Garments containing these fibers can elevate the tempature of your body, generate excessive moisture and leave you uncomfortable. Our mission in the design of our form fit tops was to bring to you a fitted base layer that will not only compliment your torso, but will guarantee your comfort during any activity.
