X-Bionic® UnderGear Bionic Vitalizer / Functional underwear

Cools when you sweat, keeps you warm when you’re cold. – Your body reacts to temperature changes with higher activity, which has a negative effect on your performance. Overheating and heat shock are comparable extremes to cold shock. 37°CCR-Technology™, developed by X-Technology® Swiss, helps your body regulate its temperature and makes “conserved energy” available for sports. Both conditions, sweating or freezing, drain the body of energy. X-Bionic® UnderGear helps the body maintain this optimal temperature range for longer.
The Bionic Vitalizer™ vitalizes and conserves energy through effective climate control with sophisticated cloth and technology. The comfortable Loose Fit clings to your body without constriction. Bionic Vitalizer™ is extremely elastic for freer movement.
