Explore waterproofness

Since 1952 we've been creating gear that works as hard as you do. Fabricated using the best materials and technologies, cut and sewn by experts to exacting standards, we create high-performance garments that keep you outside for longer. 70 years in the making, we've mastered the art of waterproof gear. Find out what sets Betacraft gear apart.

iso940 technology

The Betacraft range was named ISO940 due to its suitability in challenging weather conditions and it refers to Isobar readings.  An ISO reading of 940 indicates cloudy, windy weather with possible rain and storms.

  • How are the garments tested for waterproofness?

    The Hydrostatic Head test is used to measure waterproofness. The test involves placing a fabric sample under a sealed tube of water and measuring how much water leaks through over a 24-hour period. The measurement is given in millimeters and is known as the Hydrostatic Head. Products must pass this test to meet the British Standard, which requires a Hydrostatic Head of at least 1,500mm.

    What is the difference between waterproof and water resistant?

    Waterproof fabrics are resistant to water penetration. This is typically done using a membrane or a coating that act as a barrier, preventing moisture from permeating the fabric, keeping you dry and comfortable

    Water resistant fabrics are treated with a Durable Water Repellency coating (DWR), or a similar water repellent coating. You can tell a jacket has been treated with a water repellent coating as water will bead-up on the surface of the fabric and run off. Water resistant clothing is cheaper, less durable and may need reproofing.

    Why do you use neoprene cuffs?

    We have added Neoprene cuffs for the purpose of keeping forearms warm, dry and protected.  They provide a reasonable seal against water and mud and are comfortable thanks to the suppleness and the extendable properties of the neoprene.

    Neoprene (also polychloroprene) is a family of synthetic rubbers.  Neoprene does not degrade easily and has excellent adhesion to fabric.  It is resistance to petroleum-based products, greases, oils, weather (sun and rain) and it can tolerate temperatures ranges between -35°C and +100°C.  Neoprene is also suitable for people suffering from silicone or latex allergies.

    What is moisture wicking?

    Moisture-wicking is the process of moving moisture away from skin during physical activity.  Check the breathability ratings on our ISO940, Mamaku and Heritage ranges.
