You worked hard to find your waterproof jacket, but they lose their water resistance over time and need to be re-waterproofed. In this article, we will tell you how to re-waterproof your waterproof jacket.

Why is your waterproof jacket not repelling water anymore?

Your jacket loses durable water repellency (DWR). But it does not always happen this way. Sometimes there are other reasons, such as constant use of the jacket may cause oil and dust to build up on it. But remember dust and oil will also reduce DWR over time. So you need to clean your waterproof jacket regularly. Having an old jacket is also a reason to decrease the efficiency of waterproofing. So, waterproofing will not last forever, and that’s why you should re-waterproof your jacket.

Several factors influence your waterproofing ability

The lifetime of a waterproof jacket will depend on many factors, like the environment, the number of times you use it, how you use it, how you clean it, the area you store it, and some others.
If the quality of your waterproof jacket is excellent, it will last a long time, but you will need to reproof it during this time. Don’t forget that care and maintenance will also help to increase the lifespan of waterproof jackets.
