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 GmbH, 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 the optimal temperature range for longer. The Bionic Energizer™ reduces muscle vibration, supports muscles and joints. Thus, it optimizes physical movement and simultaneously stimulates blood circulation, leading to an improved supply of nutrients to the muscles.
