For as long as I can remember, I have been what is known as a “heavy sweater”. It was not unusual for me to soak through a shirt and a hat, or two, during a workout, and a puddle accumulate under the area that I was working out in. However, with the Brubeck 3D PRO Shirt, I honestly have never felt drier under my workout clothes. In fact, the great thing is that it optimized evaporative cooling and I actually feel cooler while I am wearing the 3D PRO Shirt. I am extremely happy with the way the shirt performs and allows me to work out longer and with more intensity.
