Men's navy blue transmission sweatshirt X-Bionic Instructor 4.0 stwrepw23m-a231

The function of the full-length unbuttoned transmission sweatshirt X-Bionic Instructor 4.0 as a second layer is to disperse moist air inside, preventing moisture condensation, and thus stabilize the cooling effect of the first layer.

At the same time, it builds channels and spaces where warm air can accumulate and store. When the weather is warm, it keeps the insulating heat of the transmission layer away from the body.
X-Bionic Instructor 4.0 sweatshirt also features revolutionary zonal compression and the patented 3D Bionic Sphere®, but this time with ThermoSyphon® technology, which further optimizes performance through more efficient thermoregulation, i.e. it cools you down when you sweat and warms you up when it's cold.

Climate Fix System located on the whole surface supports the inside system of temperature management and prevents from overheating. The waistband and sleeves finished with Aktiv-Bund tapes and the functional IDEO-Waistband® cut keep the sweatshirt in place, guaranteeing a perfect hold without slipping.

Thanks to the use of DIFFUSER technology, warm moist air rises to the collar. Then, vertical channels in the diffuser design on the inside of the collar keep them away from the neck, forming a chimney through which evaporated sweat can pass to the outside.

The sweatshirt perfectly manages bad smells thanks to SKIN NODOR® fibers, which prevent the growth of bacteria by releasing skin-neutral ions. All the functionality is complemented by two side zippered hand pockets.

The new generation of X-Bionic 4.0 products is the first to offer ultra-high quality Retina® - an extremely tight knit fabric in which thermoregulatory zones can work with the utmost precision.

Thanks to the use of multiple technologies, the body temperature is maintained at an optimal 37°C, and the muscles receive support and are ready for superhuman effort.
