Rohan review, Which? Recommended Brand

Verdict Unbeatable for the price

Customer score 87%

Average price paid £79

Pros

• Last the test of time
• Excellent fit and easily adjustable
• Comfortable

Cons

• Like most walking trousers, they're not very warm

Rohan's walking trousers tick all the boxes. Owners commended them for their comfort, durability, and how well they're made. The fabrics are breathable enough to let moisture out, and some styles unzip and transform into shorts for sunny days. One loyal customer raved: 'They cope with all weather conditions, from hot dry summer days to cold wet winter ones. They are also easy to clean and have the added benefit of drying quickly.'

These positives led to Rohan's table-topping customer score, likely helped by its reasonable prices. Customers paid an average of £79 a pair, but several owners in our survey got a bargain in the sales. 

Shop at Blacks, at John Lewis, or direct from Rohan.

Paramo review, Which? Recommended Brand

Verdict Comfortable trousers/overtrousers in one

Customer score 86%

Pros

• Superb water resistance
• Great value for money
• Breathable fabrics

Cons

• Not a huge variety of styles

Unlike most of the market, Paramo makes walking trousers that are fully waterproof; it scored five stars for this in our survey, a feat achieved by no other brand. It’s a pricey option, but justifiable given you don’t need two to invest in two sets of trousers. That’s why Paramo doesn’t feature in our overtrousers results table – it doesn’t manufacture them because it doesn’t need to. As one customer explained: '[They] keep me dry in wet conditions without overheating, and the fabric is durable yet flexible – ideal for long hikes in varied terrain.'

They fit the bill for a lot of customers; one liked the fit around the knees, and another praised the sensible pocket positioning.

Shop Paramo walking trousers directly, at Go Outdoors, Taunton Leisure, or The Mountaineer Shop.

Helly Hansen review, Which? Recommended Brand

Verdict Premium without too high a price

Customer score 79%

Pros

• Comfortable and fit well
• Easy to pull on and off
• Very good water resistance

Cons

• Not available at many retailers

Craghoppers review, Which? Recommended Brand

Verdict Premium without too high a price

Customer score 77%

Average price paid £47

Pros

• Very water resistant
• Easy to pull on and off
• Breathable and durable fabric

Cons

• Nothing major

Craghoppers' overtrousers received high marks in our survey for their weather resistance without compromising on fit or comfort. They're all-rounders, with one customer praising how 'they were reasonably priced, they keep out the water, and they fold up into a small pouch'. The brand has a broad range of styles that you shouldn't have trouble finding at major retailers.

Owners were also pleased with the fit and how the fabric 'seems tough and robust yet provides great flexibility'. It's this pliability that makes them easy to pull over walking trousers – not something all brands have yet mastered.

Browse lots of styles at Craghoppers, Cotswold Outdoor, or Go Outdoors.

What is the point of walking trousers?

While it may be tempting to wear gym leggings or jeans on hikes, walking trousers are better at keeping you protected from the elements, thorny woodland and insect bites. Plus they often have lots of useful pockets, and some even zip off at the knees to turn into shorts.

They're made with materials that wick away sweat while allowing good freedom of movement, which is useful when navigating uneven terrain and climbing hills. And while they aren't usually fully waterproof, hiking trousers should have decent water resistance and dry quickly if you get caught in the drizzle.

How waterproof are overtrousers?

You can see how waterproof a pair of overtrousers is by looking at their 'hydrostatic head' measurement. This is measured in millimetres and tells you how much water the fabric can stand before the water seeps through.

Waterproof overtrousers with a rating of up to 5,000mm will be the most lightweight and packable, but they won't cope with consistently rainy conditions. So if you're walking outside in the summer months, it's best to go for a pair with a 5,000mm rating or higher.
