Breathability
Equally as important as waterproofing, the breathability of the garment relates to its ability allow water vapor (perspiration) to escape. Volcom Outerwear ranges between 5,000gm2 - 15,000gm2, while garments made with GORE-TEX® exceed 15,000gm2. While the higher the number means the garment is more breathable, your optimal amount of breathability should be based on your planned physically activity.
