The waterproof jacket — how does it work?
A waterproof jacket is a jacket made using waterproof fabric. That may sound straightforward, but it's the starting point — let's take a closer look at how this fabric is constructed.
To ensure this waterproofness, a hardshell membrane is used, with the following objectives:
- Keep external water out (and this also provides complete wind protection)
- Allow moisture generated by the body — i.e. Perspiration — to escape
There are different types of membranes, each with varying performance levels. Waterproofness is measured in mm of water pressure, and breathability in g/m²/24h (the amount of moisture evacuated through 1m² of fabric in 24 hours). The higher-performing the membrane, the better the waterproofness and the faster moisture is expelled. Of course, external temperature and humidity conditions will also affect jacket performance.
The fabric construction also matters — there are several options for how it is made:
- 2-layer fabric: the membrane and the outer fabric of the jacket are laminated together; the membrane can optionally be protected by a mesh lining inside the jacket. Breathability and waterproofness performance are generally lower.
- 2.5-layer fabric: same principle as the above, except a film is printed on the inside of the membrane to protect it — this has the advantage of producing very lightweight jackets. It is generally used for running and trail garments.
- 3-layer fabric: this is the premium, highest-performing option — the membrane is sandwiched between 2 layers of fabric, and all 3 layers are laminated together to create an effective rain jacket that delivers protection in the most demanding conditions.
The features added to the jacket are as follows:
- The zips used are waterproof zips (essential for preventing water ingress through the zip).
- All seams are fully taped: stitching pierces the membrane, so this waterproof tape seals the seams and prevents water ingress through them — this is generally what sets hardshell jackets apart from Softshell ones.
- To improve breathability, ventilation zips are used to help limit condensation build-up inside the jacket caused by perspiration.

How do you care for a rain jacket?
To care for your waterproof hiking jacket — men's or women's — follow the instructions on the product label. Machine wash your jacket at 30°C using a specialist waterproof garment detergent and avoid fabric softeners. Preferably air-dry your jacket away from direct sunlight and any direct heat sources for greater longevity. If needed, re-waterproof your jacket using a waterproofing spray to maintain its properties.
