How to choose th cooling levels
Arc-Chill Cooling Levels
Arc-Chill products are divided into 5 cooling levels according to different Q-Max values (Q-Max is the peak value of heat flux which flows out of a copper plate having a finite amount of heat into surface of fabric after the plate contacts the fabric surface. This property is used to estimate the thermal sensation when skin touches fabrics. A higher value of Q-Max means that there is more rapid movement of heat from the body to the fabric surface resulting in a cooler-feeling fabric).
