Powerful compression within the Reflective Run Compression Tights is provided to the adductor, glute, quad, hamstring & calf, resulting in increased oxygenation, reducing the fatigue between workouts & ultimately reducing the chance of injury by up to 30%. In improving performance, 2XU hasn't compromised on comfort, with the Reflective Run Compression Tights featuring a drawstring waistband for a secure, tailored fit & a large rear pocket that can house a phone & keys. 360-degree reflective detailing also provides additional visibility in lower light conditions.
