Water column pressure is a unit of measurement used to assess the waterproofness or water repellency of textiles, including rainwear and tents. It refers to the amount of water that can be applied to the fabric before it begins to penetrate. The unit of measurement is given in millimeters (mm) and represents the height of a column of water that the fabric can withstand before water penetrates.

For example, if a material has a water column pressure of 10,000 mm, this means that the fabric can withstand a water column that is 10 meters high before water penetrates. The higher the water column pressure, the more waterproof the material.

A good water column rating in rainwear indicates the fabric's waterproofness and its ability to resist water penetration. In general, a water column rating of 10,000 mm or more is considered high and sufficient to keep you dry in moderate rain. For more intense rain or for activities in wet conditions, an even higher water column may be desirable, such as 20,000 mm or more.

Our rainwear has a water column pressure of 15,000 mm, which in 9 out of 10 cases should be more than enough to protect the active golfer against wind and water.

Hydrostatic head is an important specification to consider when choosing clothing or equipment for outdoor activities, especially in wet conditions. In general, materials with a high hydrostatic head are considered more effective at keeping the wearer dry during rain or snow.

Breathability

MVP, or Moisture Vapor Permeability, refers to the ability of a material to allow water vapor to pass through it. This is an important property in garments and textiles, especially when it comes to sportswear or outdoor clothing, including golf clothing. Breathability allows sweat vapor from the body to pass through the fabric and evaporate into the atmosphere, helping to maintain the wearer’s comfort by reducing internal humidity and preventing overheating. Materials with high breathability allow air circulation, which is essential for maintaining a comfortable temperature and preventing the accumulation of moisture inside the garment. This is especially important during physical activity or in warmer weather conditions. Breathable clothing therefore contributes to a more comfortable and functional garment that meets the wearer’s needs during different activities.
