No matter what the weather is like we always our runners to search out insulated clothing over anything else. Good insulation will keep you warm regardless of the weather or type of precipitation. Insulated clothing is also great for remaining dry and sweat free. With all the benefits its easy to see why this clothing style would be favored over others.
Some runners might assume that insulated clothing might make sweat issues worse but in reality, insulation clothing can wick and manage excessive sweat.
