This product also has a built-in fan that will give you a decent amount of airflow. Oftentimes, the fan used in your treadmill is not very powerful and doesn't do a very good job at helping you maintain a comfortable temperature. This one, however, does. Another key factor in Comfort levels while using a treadmill is the handlebars.
