When shopping for a waterproof jacket or rain poncho, you'll often see a waterproof rating measured in millimetres (mm). This rating indicates how much water pressure a fabric can withstand before water begins to penetrate it. Generally, the higher the rating, the greater the level of waterproof protection.
A 15,000 mm waterproof rating offers reliable protection in heavy rain and prolonged wet weather. It's well suited for everyday commuting, travelling, walking, cycling, and many outdoor activities, helping keep you dry even when the weather changes unexpectedly.
However, waterproof performance isn't determined by fabric alone. A well-designed waterproof jacket also needs to be breathable, allowing body heat and moisture to escape while preventing rain from getting in. Without breathability, condensation can build up inside the jacket, leaving you feeling damp even though no rain has penetrated the fabric.
That's why Rainbae combines 15,000 mm waterproof protection with 10,000 g/m²/24h breathability, creating rainwear that helps keep you dry from both the outside and the inside. The result is lightweight, comfortable protection that's designed for all-day wear.
Construction is just as important as the fabric itself. Fully taped seams seal the tiny stitch holes created during sewing, waterproof zips provide an extra barrier against rain, and our PFAS-free BIONIC-FINISH® ECO water-repellent finish encourages water to bead up and roll off the surface of the fabric. Together, these features work to maximise waterproof performance.
