Choosing waterproof jackets: how to find the right model for rain, wind and cold

A jacket described as waterproof on the product page is not automatically suitable for every British downpour. If you focus only on colour, brand or discount, you could end up with a jacket that starts leaking after a few walks, becomes too warm during exercise or leaves barely enough room for a jumper.

Pay particular attention to these three common pitfalls:

  • Water-repellent does not mean waterproof. A DWR coating initially makes rain roll off the fabric, but it does not always tell you anything about the seams or waterproofing during prolonged rain.
  • “Breathable” can be an incomplete claim. Check whether a measurement, material technology or specific ventilation feature is mentioned. Without this information, it is difficult to compare different jackets fairly.
  • A warm jacket is not always a good rain jacket. A winter coat or parka may provide insulation, but it is not necessarily designed for intensive walking, cycling or trekking.

Key features of waterproof jackets

1. Waterproofing and seams

For a proper rain jacket or hardshell jacket, not only the outer fabric but also taped or sealed seams are important. Water can enter through stitched seams, even when the fabric itself allows very little water through.

Look out for terms such as:

  • seam-sealed or fully taped seams;
  • waterproof membrane;
  • adjustable hood, cuffs and hem;
  • storm flap behind the zip;
  • a hydrostatic head rating, where one is provided.

A high hydrostatic head rating is useful for comparison, but real-world performance also depends on the construction, wear and tear, pressure from a rucksack and the condition of the coating. Always check the full product specifications.

2. Breathability and ventilation

During a brisk walk, running session or cycle ride, heat and moisture build up on the inside. A breathable jacket can help move this moisture outwards, but the result varies according to the material, activity and weather conditions.

Look for:

  • a stated MVTR rating, expressed in, for example, g/m²/24 hours;
  • underarm ventilation zips;
  • a mesh lining;
  • a fit that is not too tight;
  • room for a technical mid-layer.

According to the product description, PELLIOT states a hydrostatic head rating of 35.900 mm H₂O and an MVTR of 16.000 g/m²/24 hours for a specific fleece-lined model, measured according to the JIS method mentioned there. These are product specifications taken from the brand or sales information, not a guarantee that every user will have the same experience.

3. Fit, size and layering

An outdoor jacket should allow freedom of movement around the shoulders and arms. For commuting, a regular fit may be sufficient; for trekking or camping, extra room for a fleece gilet or insulating layer is often more practical.

Check the following before buying:

  1. your chest or bust measurement in centimetres;
  2. the back length and sleeve length;
  3. whether the size chart uses body measurements or garment measurements;
  4. whether the model is unisex;
  5. whether you want to wear a thick mid-layer.

According to the size chart, a PELLIOT hardshell in size S has a chest measurement of 112 cm and a length of 72 cm. The brand recommends considering a larger size if you want to wear thick layers. Compare these measurements with a jacket you already find comfortable, rather than relying solely on S, M or L.

Which jacket is right for your needs?

An outdoor jacket for trekking needs different features from a jacket for everyday use. A rain jacket with a lightweight shell is easy to pack away, but provides little warmth. A winter coat or parka is more comfortable in low temperatures, but can feel too warm during exercise.

  • For walking and cycling: choose a waterproof and windproof jacket with a hood, adjustable cuffs and enough freedom of movement.
  • For trekking and camping: look for hard-wearing material, taped seams, ventilation and room for several layers.
  • For running: prioritise low weight, breathability, ventilation zips and a fit that does not flap in the wind.
  • For everyday use: a trench coat, parka or simple women’s or men’s jacket may be more practical, but check that the model is genuinely waterproof.
  • For changeable weather: a 3-in-1 jacket can be worn as an outer layer, inner layer or combined jacket.

Care for a longer service life

The performance of waterproof jackets declines when dirt, detergent residue or wear and tear damage the coating. Always follow the care label, and fasten zips and hook-and-loop closures before washing. Do not use fabric softener if the product information advises against it. Allow the jacket to air-dry, and only reapply a DWR finish if permitted by the care label.

Also watch out for abrasion caused by rucksack straps and sharp branches. A hardshell may be hard-wearing, but no jacket is immune to damage. Store the jacket dry and avoid keeping it compressed in a bag for long periods.

Frequently asked questions about waterproof jackets

What is the difference between a rain jacket and a waterproof jacket?

A rain jacket is usually a lightweight outer layer for precipitation. A waterproof jacket may also feature taped seams, a membrane, wind protection and ventilation. Always check that these features are actually stated in the product description.

Are waterproof jackets warm as well?

Not always. A lightweight hardshell mainly protects against rain and wind and is often combined with a fleece or insulating layer. A winter coat, parka or 3-in-1 jacket generally contains more insulation, but may feel warmer during intensive exercise.

How do I choose the right size?

Measure your chest or bust and compare it with the size chart for the specific model. Allow room for a mid-layer. With unisex jackets and outdoor models, shoulder width, sleeve length and garment length may fit differently from a regular women’s or men’s jacket.
