Though sweat can feel uncomfortable, it's actually an ingenious way that the body manages to naturally regulate its temperature, and the new CoreSport workout apparel uses that quality of sweat to keep wearers cool while also keeping them dry. The moisture-absorbing textile from which the shirt is composed simultaneously pulls sweat from the body while keeping it in the material of the shirt, meaning that the insulating properties of the liquid still take effect even while the wearer stays dry.
Since CoreSport shirts use sweat to maintain coolness, they effectively work better as the intensity of a workout increases. The shirts also employ zinc, silver, and copper phosphorous fibers to eat up odor-causing bacteria. This means that, despite the sweat, wearers need not worry about being the smelly person in the gym locker room.
