The rain falls on the just and the unjust. With the CFS-WD Rain Jacket, you'll be comfortable enough to ponder the deeper implications of this idea instead of focusing on how wet and cold you are. WD = Warm and Dry. These two simple words become a lot more significant when you are out hunting in the elements. WD means this gear is designed to keep you in the field and focused on the hunt, not back at camp or in a vehicle fighting the damp and chill.
