Leaves residual moisture on the skin that the body does not interpret as dampness. We have no sensors for sweat. We can only perceive sweat mechanically once drops form and begin to trickle down. Only at that point do we register “wet”. Sweat Traps® absorb this moisture before it is felt, drawing it away to be evaporated and disposing of it through thermal dynamics. Only a thin film of moisture remains on the skin. Cooling is of course not possible without moisture. The Aktiv-Bund® adapts to any size of arm, leg and hip without slipping or constricting. Trap perspiration before you start to feel it. Wick perspiration away so it can evaporate using heat dynamics. A film of perspiration – too thin to be noticeable – is left behind to cool the skin. Normal thermoregulation during athletic activity follows defined rules: When the body temperature during activity climbs over a certain point, sensors in the back notify the brain via the spinal cord of the need for cooling. Only then is sweat produced to cool the already overheated body. With The Trick®, the developers at X-BIONIC® have found a new and superior way to thermoregulate. Along an insulation zone on the spine, an overheating of the body is simulated, and the brain kicks in with early sweat production.
