Ultrasoft, ventilated sports shirt featuring On/Off technology for superior thermoregulation, perfect for training and racing in warmer temperatures.

At Compressport, we never stop developing and creating. The all-new men’s On/Off SS Tshirt is the latest addition to our collection of performance sportswear, tipping the scales at 125g and bringing you technical thermoregulation and ventilation in temperate climates. The soft microfiber weave is the perfect option for runners and multisport enthusiasts seeking comfort and freshness in warmer conditions. Our signature On/Off technology has been seamlessly integrated into the fabric, providing a unique ventilation system that will keep you cool and dry when intensity builds and retain heat as the pace slows. Scientific, gender-specific body-mapping ensures optimal thermoregulation on summer days: sensitive areas are protected with a denser knit, while the perforated On/Off panels take care of breathability and ensure sweat and moisture are quickly wicked away. The Ergofit cut keeps the fabric comfortably close to the skin, out of the way of poles and brambles on the trail. Last but not least, our signature Spin Control technology helps maintain correct posture as the miles wear on, while the flat-knit seams under the arms minimise irritation and chafing. This On/Off short-sleeved T-shirt can be worn on its own, with a gilet for additional wind protection or even as a baselayer if the temperature drops. So whether you're racing a trail event, logging the road miles or exploring new outdoor activities, rest assured this high-tech shirt has you covered every step of the way.
