To determine if a rain jacket is waterproof, check the label for a high waterproof rating (e.g., over 10,000 mm). Additionally, test the seams by looking for sealed or taped seams which prevent water from seeping in. Lastly, ensure the jacket has a durable water repellent (DWR) coating that makes water bead up and roll off.

FAQs & Answers

  1. What is a high waterproof rating for rain jackets? A high waterproof rating for rain jackets is typically considered to be above 10,000 mm. Jackets with this rating can generally withstand heavy rain.
  2. How can I check if my rain jacket has sealed seams? To check if your rain jacket has sealed seams, look for visible tape on the inside or outside of the seams. Sealed seams prevent water from leaking through the stitch lines.
  3. What does DWR coating do for a rain jacket? DWR, or durable water repellent coating, helps water bead up and roll off the fabric of the jacket, enhancing its water resistance and overall performance in wet conditions.
  4. Are all rain jackets waterproof? Not all rain jackets are waterproof. Some may be water-resistant, which means they can handle light rain but are not designed to keep you dry in heavy downpours.
