If you’re performing at a medium to higher output while skiing, running, or fatbiking, you need a piece of apparel that keeps you warm but not overheated, and the Optimum Mat 2 Tights do just that! We use three different fabrics strategically placed in all the right areas to protect you from the elements while not getting saturated with sweat. The combination of our Signature Mat, Quantum 2, and Power Mesh fabrics are quick-drying and controls excessive moisture quickly and efficiently. They also have a HugFit waist, mesh inserts behind the knees for extra breathability, 2 pockets to store your essentials, and reflective logos for added visibility.
