X-BIONIC Invent 4.0 FX Long Sleeve Base Layer: Intelligent Thermoregulation for Peak Performance

Elevate your performance with the X-BIONIC Invent 4.0 FX Long Sleeve Base Layer, a masterpiece of functional apparel engineered for the ambitious athlete. Designed to serve as your ultimate first layer, this men´s long sleeve t-shirt is your key to unlocking optimal performance by maintaining the perfect core body temperature of 37°C. Whether you´re pushing your limits in training or competing at the highest level, the Invent 4.0 FX acts as your personal climate control system, allowing you to focus purely on your goals.

Experience a new dimension of comfort and efficiency, where every bead of sweat is transformed into energy. The foundation of this revolutionary base layer is the legendary, patented 3D Bionic Sphere® System, now enhanced with ThermoSyphon® technology. This complex and precisely engineered 3D structure on the chest and back is a marvel of thermoregulation. When you exert yourself and begin to sweat, it leverages the moisture to produce a tangible cooling effect. When your activity level drops and the cold sets in, its insulating channels trap warm air, creating a protective thermal buffer that prevents chilling. This decision-making fabric works in harmony with your body, ensuring you are never too hot and never too cold.

Moisture management is perfected through a network of advanced functional zones. Strategically placed Sweat Traps® under the arms capture perspiration before you even feel it, transporting it to evaporation-intensive areas to maximize the cooling process while preventing uncomfortable drips. This is complemented by the Air-Conditioning Channel®, a system of ventilation channels that continuously circulates air, wicking moisture and excess heat away from the body. This synergy guarantees you remain comfortably dry and powerful, even during the most intense phases of your workout.

The Invent 4.0 FX is crafted for a perfect, second-skin fit that moves as you do. The highly elastic Aktiv-Bund at the cuffs and hem provides a secure yet flexible hold without constricting, ensuring the garment stays exactly where it needs to be. The ergonomically optimized IDEO-Waistband features a higher cut in the back, preventing the shirt from riding up during dynamic movements and protecting the lower back from cold drafts. This meticulous attention to anatomical detail ensures total freedom of movement and unwavering comfort. This performance t-shirt is a testament to precision manufacturing, utilizing Retina® ultra-high-definition technology to ensure every single functional zone is positioned with pinpoint accuracy for maximum effectiveness.

Excellent for runs in the fall/winter - warm but allows air to go through, I also really liked the design!
