The Mizuno Breath Thermo Running Tights feature Breath Thermo Technology. A technology that captures escaping body heat and, through a patented physical reaction in the yarn, generates heat and warms the body up. The tights also feature Dynamotion Fit patterning for better anatomical fit of garment, offering freedom of movement. Additional benefits include a reflective logo and accents, designed to help you stay visible. BlindStitch is designed for anti-abrasion and enhanced wearer comfort.
