Berghaus Deluge 2.0 Pant waterproof trousers review: Warm and comfy

If you subscribe to the “there’s no such thing as bad weather, just bad equipment” mentality, then a good pair of waterproof trousers is a must. But not all are made equal – some cling, some leak and others feel like wearing a plastic bag.

You’ll be pleased to hear that the Berghaus Deluge 2.0 Pant is none of these. It’s comfortable, warm and easy to put on on a windswept, rain ravaged hillside. And most importantly, it actually keeps the water out.

There’s a few compromises though. The Berghaus Deluge is heavier and bulkier than most of the other options featured in our best waterproof trousers roundup. It's also pretty basic features-wise, without any pockets, stuff sack or ankle cuff.

Between March and June 2025, I had the chance to test these in several spring downpours. To really see how they hold up, I wore them in a range of conditions – from windy Peak District moors to drizzly but warm riverside walks. Here’s how they performed.

Waterproofing

So far in my testing, the waterproofing on the Berghaus Deluge is very effective. Over the past few months, I've found that my legs remained perfectly dry on rainy Peak District walks.

Most of the other waterproof trousers I’ve used before have just one lining, so the Deluge stands out with its two-layer design. There’s a waterproof outer shell with a solid interior lining, which turns into mesh between the knee and the hip.

As a result of the inner lining, the outer shell doesn’t sit directly against your skin. This is helpful for avoiding that muggy feeling you get sometimes inside waterproof trousers, where they don’t leak but there’s a residual dampness.

Sometimes you get a risk of water seeping through the zip, but I haven’t found this to be an issue with the Berghaus Deluge. It’s well protected by a storm flap with five side poppers, which nicely seals it in.

The higher waistband provides extra coverage, helping to keep rain from sneaking in – especially when you're bending, sitting or wearing a shorter waterproof jacket.

Breathability and ventilation

The Berghaus Deluge is thick but well-ventilated. There’s a long zip, which extends to just over midway between the knee and the hip. This means that you can open them up to get a breath of fresh air between bouts of rain, avoiding the faff of taking them on and off again.

The mesh lining is a nice touch, as it makes the tops of these trousers more breathable. These are warm trousers, mind. There’s an extra level of warmth due to the double lining. I might even venture to wear them skiing, with some warm thermal bottoms underneath.

Although the Berghaus Deluge is particularly suited to cold-weather walks, don't rule it out for the summer. Temperatures can drop fast on exposed hilltops – especially with wind and rain – so a warm, waterproof layer can be a lifesaver.

Weight and packability

For me, the main weak point of the Berghaus Deluge is their heaviness and bulk. The UK10 31in weighs 351g on my scales, which is a fair bit heavier than most alternatives in a similar size.

They’ll take up quite a bit of space in your bag too, packing down to approximately 29x21cm, which is similar to a Thermarest Neo Air camping mat.

This is the predictable side-effect of their warmth. There’s a lot of extra material compared to a standard one-layer trouser, so they’re heavier and bulkier. So if you prioritise warmth over pack size and weight, then the Berghaus Deluge is a good choice.

Size, comfort and fit

The Berghaus Deluge is super comfortable. There’s a thick elasticated waistband, with side adjustments. It’s stretchy too, so you can fit multiple extra layers underneath without it feeling restrictive.

One of the standout features of these waterproof trousers is the inclusive sizing. Unlike many competitors, they’re available in women’s UK sizes 8 to 20, with each size offering a choice of inner leg lengths from 29 to 33 inches. This means that, no matter your body shape or size, you’re likely to be able to get the fit right.

There’s also very good freedom of movement, ideal for moving fast or clambering over rocks. The fit is relaxed, so you can comfortably fit your walking trousers underneath. Thanks to the inner lining, these trousers are comfortable even over hiking shorts – something I can’t say for most waterproof trousers I’ve tried.

Features

Waterproof trousers need to be easy to put on. No one wants to be faffing about on a hillside trying to get their foot through the trouser leg as an unexpected downpour is hammering down. Luckily, the Berghaus Deluge is very easy to manoeuvre yourself into.

The side zip runs three-quarters of the way up the leg, which makes it almost like stepping into a pair of shorts, and the wide foot opening is easy to fit your walking boots through.

There’s a few features missing, though. There’s no way to cuff the bottom of the trousers, which increases the likelihood of water entering from below. There are also no pockets, which some walkers might find annoying. Some waterproof trousers include an integrated stuff sack for easy packing and storage, but not these.

Given that these trousers clearly weren’t designed with pack size or weight in mind, I wonder why these features weren’t included.

You do get free repairs with Berghaus’ aptly-named Repairhaus. I’ve never used it so can’t speak for how effective it is, but they claim they’ll stitch rips or replace zips. This is a considerable bonus, which should help to extend the life of these waterproof trousers for many years.

Verdict

The Berghaus Deluge 2.0 Pant is a warm, dependable pair of waterproof trousers, which offer good value with an RRP of £75. They’re not the lightest and they’re pretty bulky, but they’re comfortable to wear and will keep you dry for miles.
