We have several pairs of pants with a high water column rating, which means that the pants can withstand heavier and more persistent rain. The water column rating shows to what degree the garment is able to withstand water pressure before it lets water through. But a higher water column rating also makes it harder for the membrane to release body moisture. Therefore it’s important to look for shell pants with added ventilation zippers at the sides to encourage better airflow. Also look for fully taped seams and water resistant zippers when choosing waterproof shell clothing. Are you looking for waterproof clothing?
