The X-Bionic Energy Accumulator 4.0 underpants are thermal leggings saturated with the latest intelligent technological solutions for top-level athletes. Products from the Energy Accumulator line are characterised by medium compression and high insulation - they are indispensable during sports in extreme conditions and at an extremely high level.

The leggings feature 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. Thanks to these technologies, the body temperature is maintained at an optimal 37°C and the muscles receive support and are ready for superhuman effort.

The INNERLAP AIRCONDITIONING ZONE® located on the inner side of the thigh, which is less reactive to the cold and sweats more, allows for better air exchange and faster wicking, providing intensive ventilation. The legs of the shorts finished with Aktiv-Bund tape and the functional cut of the IDEO-Waistband® keep the underwear in place, guaranteeing a perfect hold without slipping.

The EXPANSSIONKNEE® technology protects the knees from cooling, even when bent, and thanks to the finely woven mesh AirConditioningSpot at the back of the knee, sweat evaporates very quickly. The ISO-Calfpad zone, consisting of corrugated channels that are located on the calf muscles, stores air to prevent chilling, especially after a prolonged standstill.

The Calesons deal 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 in which the thermoregulatory zones can operate with the highest precision.

The patented X-Bionic® Partialkompression® and many other patents create the perfect conditions for the highest muscle performance and cooling effect for the best comfort during skiing or mountain tours. Women's pink thermo-active leggings X-Bionic Energy Accumulator 4.0 eawp05w19w-p130
