Choosing a Waterproof Outdoor Jacket: Practical Buying Tips for Rain, Wind and Trekking

Choosing a waterproof outdoor jacket might seem straightforward at first. However, many shoppers fall for the same marketing claims. For example, a jacket can be water-repellent without being able to withstand prolonged rain. Similarly, a thickly padded jacket might feel warm, but it could offer too little ventilation during a brisk walk.

For UK conditions, three things are particularly important: protection from rain and wind, sufficient breathability, and a fit that allows you to move freely and wear layers. Below, you'll find what to look out for before buying a waterproof outdoor jacket.

Common Pitfalls When Buying Outdoor Jackets

1. Water-repellent isn't the same as waterproof

A Durable Water-Repellent (DWR) coating helps raindrops roll off the outer fabric. However, this doesn't automatically mean the jacket is waterproof for long periods. Therefore, always check if the product description mentions a waterproof membrane, welded or taped seams, and an adjustable hood.

A waterproof walking jacket with well-sealed seams and a close-fitting collar is more practical during prolonged downpours than a jacket that's only been treated on the outside.

2. A warm jacket isn't always suitable for physical activity

A fleece-lined jacket or a 3-in-1 outdoor jacket can be useful in changeable temperatures. While extra insulation is nice for leisurely camping, heat can build up during a fast-paced walk or climb. Look for ventilation zips, a mesh lining, and the option to zip out the inner layer.

3. The wrong size will limit its performance

A jacket that's too tight will pull at the shoulders and can restrict your freedom of movement. A jacket that's too loose will let in the wind and make layering unnecessarily difficult. Don't just look at S, M, or L; compare the chest circumference, back length, shoulder width, and sleeve length with your own measurements.

For a hardshell jacket that you'll wear over a fleece or an insulation layer, you might need to go one size up. Always follow the size chart for the specific model.

Which specifications are important?

Waterproofing and seams

Waterproofness is sometimes indicated by a water column rating in millimetres. According to the product description for the PELLIOT fleece-lined jacket for Woman Purple, the stated water column is 35,900 mm H₂O according to JIS. The same description mentions taped seams. These are verifiable product specifications, but the actual protection also depends on wear and tear, maintenance, and correctly fastening the zips and cuffs.

Also, look for:

  • a fully closing zip;
  • adjustable cuffs and hem;
  • a hood that can be adjusted with drawcords;
  • protection around the chin and neck;
  • sufficient length for cycling, walking and bending over.

Breathability

A breathable rain jacket wicks moist air away from your body. This is particularly relevant if you're using a trekking jacket during a strenuous climb or a long walk. A commonly used value is the Moisture Vapour Transmission Rate (MVTR), expressed in grams per square metre per 24 hours.

The aforementioned PELLIOT fleece-lined jacket states an MVTR of 16,000 g/m²/24h according to JIS. Think of this as a product specification, not a guarantee that you'll stay dry in all conditions. High humidity, multiple layers and a backpack can all affect ventilation.

Ventilation zips under the armpits (pit zips) are also useful. The product description for the PELLIOT Rock Shell Pro mentions longer pit zips for extra air circulation.

Layering, material and maintenance

A hardshell is usually an outer layer that protects against rain and wind. Warmth then comes from a fleece, jumper or insulated jacket worn underneath. A 3-in-1 outdoor jacket combines these layers into a single system: you can wear the shell, the inner layer, or both together.

Before you buy, check:

  • whether the jacket has a mesh lining or a warm lining;
  • whether the fabric is durable enough to be worn with a backpack;
  • whether the zips and seams are suitable for intensive use;
  • what washing temperature and drying method are permitted;
  • whether re-proofing is needed to maintain the water-repellent outer layer.

According to the product information for various PELLIOT models, recycled material is used in the outer fabric. Check the product page to see which model and composition this applies to.

Checking size, fit and use

Use this quick checklist before you buy:

  1. Measure your chest circumference while wearing a thin shirt.
  2. Compare the measurement with the size chart for the specific model.
  3. Allow room for a fleece, thermal top or insulation layer.
  4. Check that the sleeves are long enough when you stretch out your arms.
  5. See if the hood, hem and cuffs are adjustable.
  6. Check the stock for your chosen colour and size before ordering.

A waterproof outdoor jacket for mountaineering has higher requirements for durability, ventilation and freedom of movement than a jacket for urban use. A simpler model may be sufficient for a cycle ride around town. For multi-day treks, maintenance, layering options and pocket layout become more important.

Frequently asked questions about waterproof outdoor jackets

How long does a waterproof outdoor jacket last?

The lifespan depends on how you use it, friction from a backpack, washing, and how you maintain the outer layer. Wash it according to the label, close all zips and hook-and-loop fasteners, and avoid fabric softener if the product information advises against it. Over time, check the seams, coating and zips for wear.

Is a breathable rain jacket suitable for intensive hiking?

Yes, a breathable rain jacket can be suitable, but its effectiveness depends on your level of exertion, the temperature and the humidity. Pit zips and a mesh lining help with ventilation. It's best to wear several thin layers so you can better regulate your temperature and manage moisture.

What's the difference between a hardshell and a 3-in-1 outdoor jacket?

A breathable hardshell jacket is primarily a protective outer layer against rain and wind. A 3-in-1 model usually combines a shell with a warm inner layer. The hardshell is lighter and more flexible for layering, while the 3-in-1 outdoor jacket offers more versatility from a single purchase.
