The X-Bionic Energy Accumulator 4.0 LG SL is a long-sleeved thermal T-shirt imbued with the latest smart solutions and a round, raised collar to further insulate against the cold. The products of the winter line Energy Accumulator are characterised by medium compression and high insulation - they are indispensable for sports in extreme conditions and at extremely high levels.

The longsleeve features revolutionary zonal compression and the patented 3D Bionic Sphere® system with ThermoSyphon® technology to optimise performance through improved cooling. The Sweat Traps® system captures perspiration and promotes temperature balance through targeted evaporation. The AIR-CONDITIONING CHANNEL® 4.0 system provides intensive body ventilation and wicks moisture to the outside.

Sleeves and hem of the jersey finished with Aktiv-Bund tape keep the underwear in place, guaranteeing a perfect fit without slippage. The ribbed structure on the shoulders improves neuromuscular reaction time, providing balance and stability to the body, while the Expansion Ribs® technology located on the elbows, working on the accordion principle, ensures full insulation from the cold of this sensitive part of the body, even during strong flexion.

The T-shirt copes perfectly with unpleasant odours thanks to SKIN NODOR® fibres, which prevent the proliferation of bacteria by releasing skin-neutral ions. The new product generation X-Bionic 4.0 is the first to offer the ultra-high quality of Retina® - an exceptionally tight knit fabric in which thermoregulatory zones can operate with the utmost precision.

Through the use of multiple technologies, body temperature is maintained at an optimal 37°C and muscles are supported and ready for superhuman effort. Men's navy blue longsleeve with half turtleneck X-Bionic Energy Accumulator 4.0 Turtle Neck LG SL eawt18w19m-a234
