In the depths of winter, choosing the right first layer can mean the difference between cutting your training short or going all the way. Ideal for all outdoor sports, the long-sleeved On/Off literally breathes with you to regulate ventilation and protection according to the intensity of your workout. As intensity increases, your chest expands to absorb oxygen and, in so doing, the cells in the fabric open up to reduce compression and increase breathability. If your exertion diminishes, for example during a descent, these cells close up to protect you and conserve heat. Thanks to intelligent body mapping, these perforations vary in size according to the area of the torso, with larger openings in less sensitive areas such as the ribcage, and smaller ones around the neck and wrists. The result is high-performance thermoregulation and rapid drying, keeping your body temperature constant, whatever the exertion or external conditions. The tight-fitting Ergo cut supports this high-tech effect, leaving no space for drafts and ensuring maximum warmth during your workout. Our Spin Control technology is woven into the back to help you maintain correct posture. This long-sleeved T-shirt is made from seamless microfiber that stays soft and won’t rub against your skin, with natural antibacterial properties that fight odor and irritation. The scoop neck adapts to all body shapes for optimum comfort, while the raglan sleeve design frees the shoulder for full range of motion. It’s a first layer that not only keeps you warm and dry, but also supports your effort, whatever the discipline and intensity.
