High-tech long sleeve Base Layer for women, with thermoregulation for optimal performance and comfort in cold conditions.

Perfect for all sporting activities, the women's On/Off Base Layer Long Sleeve Top is made using the unique on/off technology that literally breathes with you to control ventilation and insulation depending on the intensity of your training.

As intensity increases, the chest expands to take in oxygen, and as this happens, the alveoli in the fabric open to reduce compression and increase breathability. When the effort decreases, for example when going downhill, these alveoli close again to protect you and retain heat.

The female-specific body mapping ensures that particularly sensitive areas receive more protection: the alveoli vary in size depending on the area of ​​the torso, with larger perforations in less sensitive areas such as the diaphragm and smaller ones around the neck and wrists. The result is a quick-drying, high-quality thermoregulation that keeps the core temperature stable, regardless of exertion or outdoor conditions. The close-fitting Ergo Fit supports this high-tech effect, leaves no room for airflow and ensures maximum warmth during training.

Compressport's signature Spin Control technology is woven into the back to help you maintain correct posture. The shirt is made of seamless microfiber that is gentle on the skin, with natural antibacterial properties that fight odors and irritation. The crew neck conforms to any shape for optimal comfort, while the raglan sleeve design frees the shoulder for full freedom of movement.

This is a base layer that not only keeps you warm and dry, but also supports your effort, regardless of the discipline and intensity.
