X-Bionic The Trick 4.0 Run Shirt is an innovative, incredibly practical, men's short-sleeved running shirt, designed for demanding training and starts. The fitted design looks great on the body, emphasizing the athletic figure and leaving full freedom of movement. The shirt is equipped with partial, moderate compression, which measurably supports muscle work. Additionally, it accelerates blood circulation, which additionally increases the rate of oxygen supply and the speed of removal of harmful metabolic products. The extended bottom provides additional coverage during bending, stretching, during warm-up. An important element of this specialist shirt is the innovative sweat management system. The Trick technology effectively stimulates the body to generate more sweat by adding zone insulation on the spine section. The sweat produced is then taken over and managed by special zones responsible for cooling. They maintain the ideal temperature for exercise at 37°C, significantly increasing running comfort. This effect is increased by the ThermoSyphon technology used, which takes care of the appropriate microclimate. Thanks to the use of bacteriostatic materials, the T-shirt effectively prevents the growth of bacteria and maintains a neutral smell. Produced in a modern factory in Italy using the latest Retina technology, it is made in the highest quality, without compromise. It guarantees the full effectiveness of the systems used.
