Our selection of Waterproof Jackets.
Understanding Waterproof ratings which are measured in millimetres (mm) and usually fall anywhere from 2000mm to 10,000 mm. The figure denoted indicates the amount of water pressure a fabric can withstand. That means a jacket with a 5,000mm rating will endure 5,000mm or a two metre column of water bearing down on it before it may start to leak or absorb.
10,000mm is our go to standard for Waterproof jackets on this page - which will in most cases mean a jacket also has taped (overlapping) seams. Duration of waterproofing would be 3-5 hours depending on how torrential the rain.
20,000mm - 25,000mm is locked in waterproof - Duration of being out in rain all day would suggest a 20,000mm + rating required - this will withstand 6-10 hours. It varies by brand/manufacturer and the test types they have undertaken to gain certification for the rating provided.
