After training is before training. The 2XU Power Recharge Recovery Tight is the next generation of 2XU, designed with the goal of shortening the athletes' recovery time so they can return to top performance faster. The graduated 105 denier compression promotes blood circulation, shortens the warm-up phase before exercise and then ensures faster recovery. Another special feature is the material over the ankle all the way to the sole of the foot - pressure points are reduced and support continuous blood circulation from the foot to the hips. More pressure, more power, more performance. PWXThe 2XU material PWX is antibacterial, wicks moisture away from the skin and offers UV protection of LSF 50+. The flat seams ensure highest comfort. PWX is made of high quality elastane yarn with Invista Lycra, which has been round woven for full freedom of movement and durability.
