The best waterproof mountain bike trousers in 2023 | Riding pants to keep you dry

Trail pants designed to keep you warm, dry and clean in the slop

7Mesh Thunder Pants

Whether water’s falling from the sky or splashing up from the trail, waterproof mountain biking trousers can make a huge difference to how much you enjoy wet-weather riding.


Keeping dry means you can spend longer on the trails, makes the post-ride clean-up operation much easier, and also helps you avoid the dreaded soggy chamois.

Waterproof mountain biking trousers are generally not cheap, so you’ll need to seek out waterproof and breathable materials that stand up to abuse on the trails to make sure your investment is worthwhile. However, there are bargains to be had, too.

These are the best waterproof mountain bike trousers tested in our recent winter group test.

Decathlon Rockrider All-Mountain

4.5 out of 5 star rating
Decathlon’s Rockrider All-Mountain trousers are a bargain.
Ian Linton / Immediate Media
  • Material: 88% polyester, 12% elastane with DWR treatment
  • Sizes: S, M, L, XL, XXL, XXXL
  • Weight: 307g (M)
  • Price: £40 as tested

For the money, the Decathlon Rockrider All-Mountain trousers are amazing. Even though Decathlon claims they are just water-resistant, not fully waterproof, the triple-layer seat and calf panels only started to soak through after long wet-weather rides.

The thighs and waist are made from a stretchy, breathable fabric, with a DWR coating and ample room for knee pads. This treatment does a good job of making water bead and run off, and even once the material wetted through, the trousers remained comfy and didn’t stick to our legs. The waist is secure enough to stop them slipping down, too.

A raised rear prevents mud splashing onto your back, while elastic ankle cuffs keep water from splashing up inside. The stretchy, lightweight material feels snug and dries fairly quickly.

Watch out – sizing is on the small side, especially around the waist and crotch, so consider going up. The two zipped pockets also aren’t big enough to comfortably store a smartphone.

Fox Ranger 3L Water Pants

4.5 out of 5 star rating
Get the size right and the Fox Ranger trousers have a sculpted fit that suits the riding position well.
Ian Linton / Immediate Media
  • Material: Three-layer, 94% polyester, 6% elastane with DWR treatment
  • Sizes: 28, 30, 32, 32, 36, 38, 40in
  • Weight: 330g (30in)
  • Price: £140 / $175 / €150 as tested

In the correct size (we’ll come on to that), the fit on these Fox Ranger 3L Water Pants is perfect and sculpts to the riding position well.

There’s ample space for knee pads, and tapering at the calves means they don’t flap in the wind. Elastic ankle cuffs stop water splashing upwards and the legs from riding up.

A ratchet strap provides reliable and secure waist adjustment and stops the trousers falling down once wet. They didn’t soak through during testing, keeping us totally dry after hours of torturous wet-weather riding, even once they were covered in mud.

The material feels soft and doesn’t stick to the skin, even when sweaty.

There are two zipped pockets, which are large enough for essentials; a smartphone is a squeeze and causes a bit of bunching, but doesn’t make the pants uncomfortable to wear.

As for sizing, try before you buy, because the waist sizes up quite large and adjustment is limited.

In contrast, the legs are quite short, so we ended up pairing these trousers with waterproof socks. They get quite hot on climbs, too.

POC Consort MTB Dungaree

4.5 out of 5 star rating
The Consort MTB Dungaree is worth the astronomical cost.
Russell Burton / Immediate Media
  • Material: Cordura
  • Sizes: XS, S, M, L, XL, XXL
  • Weight: 409g (medium)
  • Price: £450 / €490 / $500 as tested

If you can’t put a price on staying warm and dry, the phenomenally expensive POC Consort MTB Dungaree could be the waterproof mountain bike solution for you.

The Consort MTB Dungaree withstands filthy and soaking conditions, while proving breathable when your temperature rises – well-placed vents also help keep you cool.

The dungarees also fit fantastically and are comfortable on and off the bike.

There are zipped pockets to stash valuables, such as your mobile phone, too.

7Mesh Thunder Pant

4.0 out of 5 star rating
You’ll need deep pockets to afford the Thunder Pant.
Russell Burton / Our Media
  • Material: Gore-Tex
  • Sizes: XS, S, M, L, XL, XXL
  • Weight: 300g
  • Price: £300 / €350 / $350 as tested

The 7Mesh Thunder Pant trousers are expensive, but they’re among the best waterproof mountain bike riding pants you can buy.

These 7Mesh trousers are made from completely waterproof and highly breathable Gore-Tex Pro material.

Long waterproof leg zips enable you to pull the trousers on easily over shoes. The double zips open from the top if you need ventilation.

The cut is perfect, with no drag at the knee when riding, and the back sits comfortably high.

Endura SingleTrack Waterproof One-Piece

4.0 out of 5 star rating
The Endura onesie will mostly keep you dry, if it fits.
Russel Burton / Our Media
  • Material: Polyester
  • Sizes: S, M, L, XL, XXL
  • Weight: Not specified
  • Price: £199.99 as tested

Mountain bike onesies work well in the rain and the Endura SingleTrack Waterproof One-Piece is among the best around.

The SingleTrack looks as though you’re wearing a waterproof jacket and trousers, and it performs in the same vein.

You can pull down the  front zip and long underarm zips for ventilation when climbing. The lack of gap at the rear stops blasts of icy water shooting up your back.

The ExoShell20 fabric is sufficiently waterproof and breathable to keep you dry, except in deluges and sweaty climbs.

Side pockets can hold a phone and the hood tips over a helmet.

Fit is iffy across the shoulders and waist, but the arms and legs are tailored better.

Troy Lee Designs Resist

4.0 out of 5 star rating
The Troy Lee Designs waterproof pants resist the wet and cold.
Steve Behr / Immediate Media
  • Material: Bluesign-certified 10k/10k waterproof stretch fabric
  • Sizes: 30, 32, 34, 36, 38, 40in
  • Weight: Not specified
  • Price: £149 / $149 as tested

The Troy Lee Designs Resist trousers are made of a stretchy, eco-friendly fabric that’s very breathable and copes well with rain, with taped seams to keep out water.

They’re not rustly and the fabric is a little warmer than some on cold rides, while zipped thigh vents help on warmer rides.

There are three zipped pockets and waist adjustment to ensure a good fit, while the high waistband and reinforced seat ensure you don’t get wet from wheel spray.

The legs taper nicely, so they don’t flap around even when wet or muddy, but still leave enough room to wear knee pads underneath.

Although they coped with most conditions, the Resists did wet out at the front of the legs in prolonged downpours, but this never left us feeling cold at the end of a ride.

Also consider…

The following trousers scored less than 4 out of 5 in our reviews but are still worth considering.

Gore C5 Gore-Tex Paclite

3.5 out of 5 star rating
The Paclite trousers kept us dry, not wetting through for the entire test period, but ventilation is an issue.
Ian Linton / Immediate Media
  • Material: Gore-Tex Paclite Plus 100% polyamide
  • Sizes: S, M, L, XL, XXL
  • Weight: 167g (M)
  • Price: £180 / $200 / AU$265 / €200 as tested

True to Gore’s claims, the C5 Paclite trousers kept us dry during testing and didn’t wet through or leak during the post-ride hose-down.

There’s a raised panel at the rear, which helps reduce the amount of water and mud splashing onto the small of your back. At the waist, a drawcord, fastened with a knot, stops them falling down once wet.

They fit true to size and, while there isn’t much stretch in the fabric, there was no excess tension around the crotch or hips. The large, calf-height zip makes it easy to take them off with shoes on. They’re light too, at 167g for our medium pair.

However, the lack of thigh vents means these trousers get quite hot and, once we got sweaty, our legs stuck to the inside. We found they tugged knee pads down, especially when pedalling seated.

The ankle cuff poppers aren’t as good as an elasticated cuff and don’t feel very refined, considering the high price. We struggled to fit a modern smartphone in the single pocket.

Alpkit Parallax

3.0 out of 5 star rating
The Parallax trousers from Alpkit are lightweight and highly packable.
Ian Linton / Immediate Media
  • Material: 2.5-layer, 100% nylon with PU membrane
  • Sizes: S, M, L, XL
  • Weight: 182g (S)
  • Price: £80 / $100 / AU$147 / €90 as tested

The Alpkit Parallax trousers deal with sweat well, the inside only getting wet on very slow climbs. Once damp (we’ll come on to waterproof performance), they were still comfortable against our skin and didn’t cause knee pads to fall down.

We like the light feel and the way they pack easily into the supplied bag. The elasticated waist and adjustable pull-cord meant we could tighten the pants so they didn’t fall down, even when covered in mud and water.

On the flip side, the fit is fairly baggy, especially around the calves, where the material flaps in the wind. Adjusting the Velcro ankle cuffs doesn’t reduce the volume either.

While the trousers resisted full water penetration during testing, the 2.5-layer material did wet-out quickly, with the outer layer getting soaked through and making the trousers feel damp on the inside, even though the water didn’t get all the way in.

This suggests the DWR coating can’t cope with the abrasion and rubbing of bike use. When we hosed them down at the end of a ride, the seams leaked, letting water in.

These are also available in a women’s cut.

Buyer’s guide: what to look for when buying waterproof MTB trousers


Waterproof trousers will make wet-weather riding a much more pleasant experience.
Ian Linton / Immediate Media

Waterproof materials are typically made up of two or three layers, including a waterproof membrane, often backed by a softer material against your skin and sandwiched between a tougher external layer (or ‘face fabric’).

A fabric’s waterproof rating will demonstrate whether it’s able to stand up to drizzle or heavy downpours, and is measured by a material’s resistance to water before it leaks through, conducted under lab conditions.

The higher the number, the more resistant to water ingress and bad weather conditions the material will be, with ratings of 16,000mm and over suitable for wet conditions and 20,000mm and above among the best.

Seams are an obvious weak point in any waterproof fabric, so they are often sealed and taped internally to try to stop water getting in.

DWR treatment (Durable Water Repellent) is often used on the external surface of the fabric to help precipitation or trail spray bead off the surface.

As this treatment degrades over time with laundry cycles, it can be reapplied to the fabric using reproofing sprays or washes. Look out for PFC-free DWR treatments for the most environmentally friendly solution.


Look for robust, waterproof panels on those areas most exposed to water and dirt.
Ian Linton / Immediate Media

Mountain biking trousers aren’t often made completely from waterproof materials, but instead use a combination of strategically placed panels of waterproof, water-resistant and breathable fabrics to give the best overall performance.

The areas that typically get wettest include the seat and backs of the legs, from spray off the back wheel, so these usually feature the most robust waterproof materials and taped seams.

Some trousers will feature areas of DWR-treated water-resistant fabrics, such as on the front of the thighs, because these are less likely to get as wet. The idea here is to provide some protection from rain or trail spray, though the fabric isn’t necessarily fully waterproof.

Breathability and ventilation

Vents like this will improve airflow when working hard or when conditions warm up.
Ian Linton / Immediate Media

The flip side of waterproofing is breathability, as anyone who’s sweated buckets inside cheap waterproofs (whether that’s a jacket or trousers) will be all too aware.

Maintaining airflow, ventilation and sweat evaporation while keeping water out is the holy grail for any waterproof product and can be achieved by using high-tech breathable fabrics and strategically placed vents.

Some trousers have zip-able vents to help maintain airflow when it’s not bucketing it down or when riding uphill, typically found on the upper thighs.

The Water Vapour Transmission rating (WVTR) measures how breathable materials are, by testing how much water vapour can travel through the material in given conditions. The higher the rating, the more effective it will be at keeping you comfortable during higher-intensity riding.

Look for ratings of 20,000g/m²/24hr and above for good breathability.

Fit and cut

Elasticated cuffs help keep your legs dry and stop the fabric catching on the drivetrain.
Ian Linton / Immediate Media

Waterproof riding trousers should fit similarly to conventional MTB trousers, with a tapered lower leg to reduce the risk of getting the fabric caught in the drivetrain or flapping, and an adjustable waistband to tailor the fit. A higher cut at the back also gives extra splash protection.

Ideally, you’ll want a snug but non-restrictive fit: too loose and you could risk the trousers sagging; too tight and they’ll be uncomfortable or restrictive. Look out for elastane blend materials to help give extra stretch, and make sure there’s plenty of room for you to wear knee pads underneath too.

Some waterproof trousers are designed to be worn over your normal riding trousers, with full-length zips for ease of getting on and off, and a slightly looser fit so you can layer up underneath.


Pockets are useful for storing essentials.
Ian Linton / Immediate Media

Pockets with a waterproof lining and waterproof zip are best for storing valuables.

These should be located away from the hip area, such as on the outer thigh, so they don’t interfere with leg movement when pedalling.

Other features

Reflective detailing is useful if you ride at night.
Ian Linton / Immediate Media

Besides countering the elements, waterproof trousers must also be robust enough to endure the rigours of mountain biking, so look out for additional features including abrasion-resistant panels.


If you’re planning on mountain biking at night, reflective details are another bonus.
