Valldoreix
Heat Activated Training Tee Off-Black/White
Short-sleeved performance t-shirt in off-black, engineered with thermochromic technology that reacts to heat and changes color during play. Cut in a relaxed boxy silhouette and built from lightweight performance fabric, it is designed to move freely on court while creating a visual response to the intensity of the match.
The color transformation is achieved through thermochromic pigments embedded within the fabric. At lower temperatures, the garment appears off-black. As the fabric warms from body heat, sunlight, or rising ambient temperatures, the pigments become transparent, revealing a crisp white base layer beneath. The result is a dynamic transition from off-black to white that evolves throughout play and gradually returns as the fabric cools.
A nod to the bold experimentation of tennis in the early 2000s, reimagined through modern fabric technology. Designed to stand out on court.
Made from 180gsm performance fabric with front and back serigraphy detailing.
Technical Details

Important info: Wash on a cold cycle. Do not iron or rub the fabric, as this may damage the heat-reactive effect. Also, please check the size guide, as this tee fits slightly shorter than our other styles, and we recommend sizing up for the best fit.
