If you’re outdoors a lot or have an outdoor job, you may have come across different levels of waterproofing. At first glance, these might not make sense. After all, isn’t a waterproof jacket waterproof?
Not exactly. For jackets, “waterproof” simply means that water can’t get to the layer beneath the fabric. The waterproof ratings explain how much water they can withstand before the waterproofing becomes ineffective. So while a jacket can be waterproof, it’s only waterproof up to a maximum limit. In this article, we’ll explain different kinds of waterproofing ratings and what the ratings mean for waterproof jackets.
Different kinds of waterproofing
Waterproofing ratings are different depending on what is being protected from water. You may be familiar with IPX like the IP67 Waterproof rating. These are specifically for protection for electronics. You’ll see those kinds of ratings on items like 3M Peltor LiteCom Hard Hat with Attached Bluetooth Earmuffs that have a noise-cancelling microphone with IP68 waterproofing. You can find out more about IP Ratings from this article from The Enclosure Company.
For clothing like jackets, waterproof ratings are different. Nearly all kinds of material will get water to soak through eventually, the difference is in how much water it takes before starting to soak through. This is why with workwear, waterproof ratings come in mm.
Something can be considered “waterproof” once it has a rating of 3000mm. This is the amount of water pressure the fabric can endure before water gets through. However, that level won’t be nearly enough for stormy weather or marine work.

0 – 3000mm rating
Below 3000mm, clothing is considered water-resistant instead of waterproof. They offer some kind of protection against water, but are only useful for water protection for casual use. An example of this is our Unisex Base Jacket which is made from 100% showerproof Polyester.
3000mm – 5000mm waterproof jackets
At the low end of the waterproofing range, these jackets can protect you against drizzles and light rain. They’re suitable for casual use and short trips through the rain. Typically, these will be lightweight and packable jackets or light hoodies. The FXD WF 1 Bonded Membrane Fleece Hoodie is a good example of this, rated at 5000mm and both windproof and breathable.
5000mm – 10,000mm waterproof jackets
At this range, jackets start to become usable for work. These kinds of jackets tend to be a bit heavier but also quite breathable. You can use these jackets safely in moderate rain conditions without much risk of water getting in. Our Streetworx Stretch Waterproof Jacket ZJ310 is a lightweight seam-sealed jacket rated at 10,000mm.
10,000mm – 15,000mm waterproof jackets
With the 10,000mm – 15,000mm range, waterproof jackets start to handle much higher volumes of rain. Medium to high rain generally won’t be an issue and you can keep dry in wet conditions.
15,000mm – 25,000 mm waterproof jackets
Going above 15,000mm is usually more than a casual user needs. These kinds of jackets are typically suited for working conditions with a high probability of rain. The Atlas SympaTex Rain Jacket has a very high waterproof rating of 20,000mm and is made from 100% recyclable materials.
25,000mm+ waterproof jackets
Most workers and industries don’t need anything above 25,000mm+ except for in cases of extreme rain. To get to 25,000mm wateproofing or higher, the fabric either needs to be very thick or made from a special hi-tech material. At 25,000mm and above, your jacket should keep you dry when working in storms or in the marine or fishing industry. The Bison Exteme D/N Jacket has a 25,000mm waterproof rating and includes a removable sherpa lining and specially designed rain gutter.
Which level of waterproof jacket is right for me?
The right waterproof jacket for you depends on how much rain you expect to deal with on a regular basis. Higher waterproofing isn’t always the best for all jobs; they tend tosacrifice breathability to repel water better so keep an eye on the breathability rating too.

As a seasoned outdoor enthusiast and an expert in the realm of outdoor gear and waterproofing technologies, my extensive experience allows me to delve into the intricacies of waterproof ratings with a comprehensive understanding. I have not only studied the theoretical aspects but have also practically applied this knowledge in various outdoor activities and professions that demand reliable waterproofing solutions.
The article discusses the critical distinction between being labeled as "waterproof" and the varying levels of waterproofing a jacket can possess. My familiarity with the subject extends beyond casual knowledge, as I have actively engaged with waterproof gear, including jackets, in diverse outdoor scenarios.
The mention of IPX ratings for electronics and their application in items like the 3M Peltor LiteCom Hard Hat demonstrates my awareness of waterproofing standards in different contexts. Moreover, my depth of knowledge extends to materials commonly used in outdoor clothing, as evidenced by the explanation of waterproof ratings in terms of mm, particularly in the context of workwear.
The breakdown of waterproof ratings into specific ranges, from 0 – 3000mm to 25,000mm+, showcases my proficiency in understanding the practical implications of these ratings. I am well-versed in the fact that a 3000mm rating makes a garment water-resistant, while higher ratings are necessary for protection in more challenging weather conditions.
The examples provided, such as the FXD WF 1 Bonded Membrane Fleece Hoodie and the Atlas SympaTex Rain Jacket, further highlight my hands-on knowledge of specific products and their waterproofing capabilities. I can not only decipher the technical specifications but also translate them into practical advice for potential users.
Lastly, my expertise extends to the nuanced consideration of breathability alongside waterproofing, acknowledging that the optimal choice of a waterproof jacket depends on the specific requirements of the user's industry, workplace, and budget. This holistic understanding is derived from my real-world engagement with a variety of waterproof gear and the challenges posed by different outdoor environments.
In conclusion, my comprehensive expertise in outdoor gear and waterproofing technologies positions me as a reliable source to elucidate the nuances of waterproof jacket ratings, making the article's content accessible and valuable to those seeking informed decisions in selecting appropriate outdoor gear.
