Ionx Base Layer Short Sleeve Cold Tee White. 65% Nylon 21% Polyester 14% Lycra. Colour White. Canterbury Base Layer Ion X delivers ionic energy to the body through a negatively charged electromagnetic field. Ionisation is the process which occurs when atoms become positively or negatively charged. Ionisation is a natural process which occurs during electrical storms or in the vicinity of waterfalls. enhanced Performance: the increased flow of oxygen-enriched blood brings more energy to the muscles, which increases the average power output, improving speed & strength. Accelerated Recovery: The increased blood flow more effectively flushes out residual waste products, such as lactic acid, which are left in the muscles after high intensity activity. Recovery is accelerated, therefore training or competition can begin again more quickly.
