Stay hydrated!!!
This is a myth perpetuated by the people that want you to purchase their clothing. Wicking moisture away from your skin make you hotter! It is the evaporative process that provides cooling. Remove that process and you will tend to get hotter. The only time you want to wick away moisture is when it's cold!
