The Compressport On/Off Base Layer LS Top is a high-tech long-sleeved base layer with body-mapped thermoregulation for optimal performance and comfort in cold conditions.

Product Description

In the heart of winter, choosing the right base layer can mean the difference between staying out or cutting your session short. The long-sleeved On/Off Base Layer Top is ideal for all outdoor sports and is made with our unique On/Off technology that literally breathes with you to regulate ventilation and protection depending on the intensity of your workout. As intensity increases, your chest expands to take in oxygen, and the alveoli in the fabric open up to reduce compression and increase breathability. When your effort decreases, for example when descending, these alveoli close again to protect you and retain heat. Thanks to smart body mapping, these perforations vary in size depending on the area of ​​the torso, with larger openings in less sensitive zones such as the rib cage and smaller ones around the neck and wrists. The result is fast-drying, high-performance thermoregulation that keeps your core temperature constant, regardless of exertion or external conditions. The close Ergo fit supports this high-tech effect, leaves no room for air droplets, and ensures maximum warmth during your workout. The signature Spin Control technology is woven into the back to help you maintain correct posture. The shirt is made of seamless microfiber that is soft and harmless to your skin, with natural antibacterial properties that combat odors and irritation. The crew neck adapts to every body type for optimal comfort, while the Raglan sleeve design leaves the shoulder free for full range of motion. This is a base layer that not only keeps you warm and dry but also supports your efforts, regardless of discipline and intensity.
