Best mountain bike jackets in 2024 | 22 jackets rated by our expert testers
Patagonia Dirt Roamer
- £210 / $229 as tested
- Protection: Water-resistant
- Pros: Excellent cut, works as a versatile layer
- Cons: Not suited to heavy downpours
Although not strictly a waterproof, this weatherproof, packable jacket is a true all-rounder that's perfect for those days with quick changes in weather.
The DWR finish keeps water off well and dries quickly when wet, but this is not a choice for the worst conditions.
The fit is exceptional, with a dropped tail, generous sleeves and over-helmet hood
It's so breathable that it easily transitions from cooler starts to warmer finishes. Our tester found it ideal for spring and autumn rides in the UK with just a baselayer underneath.
7Mesh CoPilot
- £250 / €280 / $280 as tested
- Protection: Waterproof
- Pros: Laidback cut; wards off bad weather
- Cons: Larger zip pulls would help when wearing winter gloves
The updated version of the 7Mesh CoPilot jacket is more orientated towards bikepacking, having a looser fit and readily packing up into its back pocket.
You can then use the pocket straps to wrap the CoPilot to your bike frame.
The CoPilot's hood can be worn over your helmet and stays in place once you've tightened the adjustment cords.
By retaining its predecessor's Gore-Tex Paclite Plus material, the 7Mesh CoPilot keeps you dry on multi-hour wet rides.
Endura MT500 Freezing Point Jacket
- £164.99 as tested
- Protection: Softshell
- Pros: Impressive flexibility with sleek styling; good balance between warmth and breathability
- Cons: Hood doesn't fit well over a helmet
The MT500 Freezing Point is made out of a four-way stretch thermal softshell fabric, and features PrimaLoft Gold Active insulation on the front panel to ward of wind chill.
Designed for colder days, the jacket warms up quick when climbing but long pit zips allow you to regulate temperature without taking the jacket off.
A PFC-free DWR finish keeps the water out efficiently, while the tailored fit allows for for extra layers beneath.
Although Endura don't claim the hood is helmet compatible, we found that it could squeeze over but it was quite restrictive.
Gore Endure Jacket
- £230 / €230 / $230 as tested
- Protection: Waterproof
- Pros: Well-considered fit; plenty of technical features
- Cons: Continued re-proofing required
The Gore Endure Jacket's styling and fit is relaxed enough to wear for everyday riding and even when off the bike, but its performance is top notch.
The Gore-Tex Paclite Plus material is claimed to be breathable and waterproof, but it does require regular reproofing.
There's a dropped tail to keep muck off your back. You can wear the peaked hood over your helmet and it's easy to adjust.
The Gore Endure jacket has two pockets and packs down itself into a pocket or hip pack.
Patagonia Micro Puff Hoody
- £250 / $299 as tested
- Protection: Water-resistant
- Pros: Impressively warm; packs down into its own pocket
- Cons: Expensive; outer fabric might not resist long-term abuse
The Micro Puff Hoody from Patagonia is a lightweight, soft-shell garment that looks good both on and off the bike.
It's seriously warm thanks to the use of synthetic PlumaFill insulation and the DWR coating is effective, but we'd still recommend using this as a mid-layer in the worst of conditions.
Despite minimalist looks and a fit that's neither tight nor slack, it's full of useful storage pockets. It's impressively packable too, folding down neatly and easily into its own pocket. Our tester loves his so much that he's rarely seen without it.
POC Signal
- £320 / €350 / $350 as tested
- Protection: Waterproof
- Pros: All-weather protection; smart and well-considered details
- Cons: Price
Even in the worst conditions, the Signal kept us dry and comfortable. The material is breathable when working hard, and there’s further ventilation from underarm gills, a back vent and the two-way zip.
Its lightweight, three-layer ripstop fabric is soft enough to wear against bare arms. The fit is close but not restrictive, and styling is sleek. It packs into its own zipped back pocket, and has a smaller side pocket too.
Design is efficient across the board – it has a good interface between hood and helmet straps, shaped cuffs that sit just right, and a long drop back that hangs perfectly flat, courtesy of side elastic in the hem.
Scott Insuloft Superlight PL
- £220 as tested
- Protection: Insulated jacket with DWR outer
- Pros: Lightweight and highly packable; great fit
- Cons: Expensive
Scott's Insuloft Superlight PL is very comfortable, with its lightweight and well-cut fabrics helping it look good on and off the bike.
It features a DRYOzone DWR outer layer, which stood up to the harshest of conditions and shed even the toughest downpour. The breathability impressed too, avoiding chill from sweat build-up.
The performance of the Scott Insuloft Superlight PL matches its high-end price, and the ease of packing into the chest pocket means you can always bring it with you.
ThruDark Skirmish
- £345 as tested
- Protection: Waterproof
- Pros: Cross-functional design; waterproof and breathable; excellent cut
- Cons: Price
This jacket from new UK brand ThruDark is a cross-functional piece designed for extreme weather.
A fully adjustable hem and hood enable you to seal it tight, with a deep yoke vent on the back and underarm perforations for airflow.
It’s hard to get a great fit both on and off the bike, but this Dorset-based outfit has managed it. The Skirmish’s long tail drops into position, its shaped cuffs fall perfectly over the backs of the hands, the sleeves articulate with every movement and the hood’s slightly stiffened peak keeps the rain out of your eyes.
The three-layer eVent fabric breathes well and is durable and in torrential rain, we still didn’t overheat. With nifty details, such as an internal chest pocket, this jacket is worth considering despite the very high price.
Endura GV500
- £160 / €180 / $200 as tested
- Protection: Waterproof
- Pros: Fantastic value; high levels of protection
- Cons: Slightly tight under the arms
The Endura GV500 has many of the features and performance of much pricier waterproof jackets.
Its hood goes over a helmet without obscuring your line of sight. A lowered tail protects your back and the GV500 can be stowed in its single chest pocket.
The cut treads the right line between slim and tight, so the GV500 doesn't restrict your movement, except to a degree in the arm areas.
The Endura GV500 is comfortable whichever layer you wear beneath it. Waterproofing is impressive and breathability isn't far behind.
Giro Ambient Jacket
- £119.99 as tested
- Protection: Softshell
- Pros: Impressive warmth and waterproofing; large hood aids movement
- Cons: No women’s XS option; heats up rapidly on the climbs
The Giro Ambient is a three-layered fleece softshell featuring a four-way stretch fabric on the outer. Although not fully waterproof, we found it kept most of the water out on long, wet rides, while the hood provided good protection without getting in the way.
Best suited to cold days, we found the jacket overheated above 5 degrees, with the laser-cut vents in the armpits doing to little to stop this resulting in a full unzip.
Large, well-placed pockets enable you to carry your belongings without them getting in the way of your riding. Lycra gaiters complete with thumb holes make sure your sleeves stay in place.
Rab Zenith
- £250 / €300 / $300 as tested
- Protection: Waterproof
- Pros: Great breathability; cross-functionality for other outdoor pursuits
- Cons: Cut might not suit all mountain biking situations; expensive
Featuring easy-access front pockets, a large wired peak hood that’ll fit over a helmet, long pit zips and a longer hem than a dedicated cycling jacket, the Rab Zenith is a multi-use waterproof that won’t leave you having to compromise.
Exceptional breathability thanks to the Gore-Tex Paclite Plus construction has proven to be a major advantage, with additional ventilation features should you need them on warmer rainy days.
The fast-drying material also beads water well thanks to the DWR coating, and Rab offers a reproofing service for this to keep your jacket performing as new, season after season.
You’ll need those deep pockets to afford this top-tier option, but it’ll pay off in the Zenith’s practical versatility.
dhb Trail Waterproof Jacket
- £150 / €170 / $190 / AU$273 as tested
- Protection: Waterproof
- Pros: Great value for the quality; well-considered fit
- Cons: Hood doesn’t work over helmet for taller riders
With many features that are typically reserved for higher-price jackets, the Trail waterproof from dhb reflects the brand’s solid reputation for great-quality, excellent-value cycling kit.
The high-stretch, 20k/20k material features a three-layer construction that’s durable, teamed with long, mesh-lined pockets that double up as vents.
Shaped cuffs, a fold-away hood that also fits over a helmet, and a clever drop-hem adjustment all contribute to the great fit of the jacket.
The stretch fabric comes into play on the bike, meaning you can achieve a slimmer fit without limiting the freedom of movement.
Berghaus Changtse
- £290 / €350 as tested
- Protection: Waterproof
- Pros: Technical construction; lots of vents and pockets; do-everything credentials
- Cons: Expensive
The Changtse is absolutely packed with features. It uses a number of different Gore-Tex waterproof fabrics across the jacket for optimal performance in each area.
There’s Paclite Plus on areas such as the chest and arms, which are more prone to wear, while the core is made from Active Shell for greater breathability.
It’s not a bike-specific jacket, but the cut and flexibility are good enough that it never feels like a compromise.
Endura MT500 Waterproof Jacket II
- £230 / $329 as tested
- Protection: Waterproof
- Pros: Adjustable helmet hood; multiple pockets; works well with backpack
- Cons: Price
An update to the popular MT500 jacket only adds to the appeal of this excellent fully featured waterproof layer.
The three-layer waterproof fabric performs well and, combined with the refined fit and plentiful storage, adds up to a garment that does not disappoint.
The 536g (large) MT500 kept our tester both dry and comfortable during challenging conditions.
It’s also been designed to work well with a backpack, and we can confirm it does just that.
On Waterproof Anorak
- £320 / €359.95 / $359.99 as tested
- Protection: Waterproof
- Pros: Light and athletic fit; hydrophobic inner helps wick perspiration away
- Cons: Hood isn’t helmet-compatible
On’s Waterproof Anorak isn’t a cycling-specific jacket, but its performance impresses nevertheless. The half-length zip isn’t perhaps the most practical option for getting On’s Waterproof Anorak on and off while on the bike, but it does reduce bulk a bit, and fashionistas will likely welcome the alternative look.
We didn’t notice any compromise in breathability either, possibly thanks to the hydrophilic elements on the innermost layer of the jacket's three-ply fabric.
It’s an especially good jacket for those who do a bit of running as well as cycling because it can readily share duties across the two sports.
Patagonia Dirt Roamer Storm
- £290 / €320 / $290 / AU$490 as tested
- Protection: Waterproof
- Pros: Comfortable fit; storm-resistant; practical features
- Cons: Over-head style might not be for everyone
The premium Patagonia Dirt Roamer Storm jacket is the completely waterproof version of the Dirt Roamer jacket that also figures in this list.
The Dirt Roamer Storm has to be worn with the hood over your head or helmet. In order to remove the jacket, you'll have to take off your helmet.
To reduce how often you need to do so, Patagonia has placed zipped vents on the side and front of the jacket.
The Dirt Roamer Storm's triple-layered H2No shell wicks sweat as well as repelling rain.
Rab Arc
- £200 / $260 as tested
- Protection: Waterproof
- Pros: Sturdy with good warm and durability; style works on and off the bike
- Cons: Can over overheat on mild days
The Rab Arc jacket isn’t made specifically for cycling, but this compromise means it brings more versatility to the table.
In particular, the cut is a little boxy on the bike, but the 422g jacket feels great when you’re not riding – unlike cycling-specific jackets, which are often poorly shaped for off-bike use.
Generously sized front pockets and a hood that fits comfortably over a helmet only further its credentials.
The fabric is three-layer rip-stop with a high-quality and durable feel. This adds a bit of weight and a fair amount of warmth, but it also means it’s more likely to stand the test of time.
The Rab Arc has now been replaced with the Rab Arc Eco, made with 100 per cent post-consumer recycled polyester.
Rab Cinder Borealis
- £100 / $120 / €140 as tested
- Protection: Wind-resistant
- Pros: Good cut with accurate sizing; breathable; packs down well
- Cons: Poor wet weather ability; would benefit from another pocket
The Rab Cinder Borealis offers a comfortable fit and works well to fend off the chill of autumn and spring.
A tailored cut makes the jacket well suited to riding, with a snug fit keeping ballooning and flapping to a minimum.
The Cinder Borealis packs down small into a single rear pocket, making it easy to carry on unpredictable days.
We found the amount of pockets and wet weather ability to be a limitation with the jacket, with the fabric not responding well to anything more than a quick shower.
Troy Lee Designs Mathis
- £140 / $150 / €180 as tested
- Protection: Water-resistant, insulated
- Pros: Good levels of warmth while remaining breathable; lightweight with a good pack size
- Cons: Neck is a tad baggy and the hood is prone to flapping about
The Troy Lee Designs Mathis does a good job of keeping you warm on cold rides thanks to its insulated core.
Breathable side panels keep the Mathis from overheating keeping you from getting warm and clammy on cold days.
Its lightweight and small pack size makes the Mathis no chore to carry reducing the pain of over-dressing.
The hood and neck area is quite baggy leading to flapping during high wind or high speed, but the casual look of the jacket makes it wearable on and off the bike.
What to look for in a jacket for mountain biking
Water-resistant zips
These keep wind and rain out without the need for a storm flap. They’re easy to identify by the smooth seal that closes protectively over the teeth, but can be stiff to use.
Two-way zips
Double zips allow you to open the jacket from the bottom as well as the top to help you cool down faster – useful when you’re working up a sweat.
Drop tail
A longer back to ensure your lower back is covered and help keep mud and spray off the seat of your shorts or riding trousers.
Adjustability here is also handy, so look for elasticated drawcords to help you cinch in the hem. Check the length is right for you by jumping on a bike when you’re trying a jacket on.
Dropped cuff
Cuffs that are shaped to extend over the back of the hand integrate with gloves more smoothly than those with Velcro adjusters, and channel rain over, rather than inside, your gloves.
They’re also more comfortable to wear, moving freely with your body as you ride, and shed water better, because there are no creases for moisture to gather inside.
Lined collar
A fleecy inner collar not only feels more comfortable against your skin, it absorbs stray drips before they run down your neck too.
Helmet-compatible hood
A hood that goes over a helmet is our preferred style for practicality, although some riders like one that fits underneath. Check it can be cinched in to reduce its volume and keep your peripheral vision clear.
Vents
Vents help heat and sweat to escape. They can either be zipped or open with gill-like slits. If you wear a hydration pack, check the straps don’t obstruct the jacket’s vents, and look for double-ended zips, which give more ventilation options.
Jackets explained
Breathability
Multi-layer fabrics can be both waterproof and breathable because the membrane layer has lots of tiny pores. These pores are large enough for water vapour to escape, but too small for water droplets to pass through.
The breathability is the rate at which a fabric allows heat from inside to escape, in the form of water vapour, measured as the Water Vapour Transmission Rating (WVTR).
Search for ratings over 20,000g/m²/24hr for good material breathability. There is, however, a limit as to how breathable any waterproof fabric can be if you’re riding hard or the weather is warm.
Waterproofing
The waterproof rating of a fabric will tell you if it’s suitable for wet-weather riding, from fine drizzle through to a prolonged downpour. This is measured in a lab, testing the height of a 1in diameter column of water that a fabric will withstand before it leaks, measured in millimetres.
Higher numbers here indicate a greater resistance to water seeping through. As a guide, 10,000mm is a good benchmark, with 20,000mm better for prolonged or extreme conditions.
If you’re looking for a waterproof for wet-weather riding, double-check that the seams are taped: otherwise, these are weak points for waterproof garments.
Insulation
Insulated jackets come in various forms, with fleece and baffled constructions both used to trap warm air to create a barrier between you and the outside cold.
Insulated jackets aren't usually as waterproof as other jackets, because more breathability is needed to stop chill from sweat build-up on the inside.
Mountain bike jackets will usually use a synthetic fill in baffled designs because even the most hydrophobic of down will struggle to cope with the constant washing that muddy clothes need.
The amount of fill is a good indicator as to how warm a jacket will be, because the more there is, the more air will be trapped. However, jackets with less fill can be just as effective when used with other layers.
Three-layer fabric
A fabric consisting of an outer shell over a waterproof membrane with an inner backing.
This lining helps protect the membrane and prolong the life of the jacket. It also gives a smoother feel against the skin, and may have wicking properties, too.
2.5-layer fabric
Here, the waterproof membrane has a thin coating applied to the inside, rather than a proper lining. This type of jacket is often typified by a rubbery feel, but the ‘half’ layer makes the material lighter and more packable.
DWR
Durable Water Repellent treatment (DWR) is often used on the outside of garments to help water and dirt bead off the material’s surface without soaking in. You’ll commonly find this treatment on waterproof jackets, trousers and baggy shorts.
A DWR treatment can wear out or wash off over time, but a little TLC can make your jacket feel as good as new. Read our guide to reproofing a waterproof jacket.
PFCs
Perfluorinated and poly-fluorinated chemicals are often used in the production of DWR finishes, but break down very slowly once released into the environment. Many brands are now moving to PFC-free materials, so check the blurb.
When it comes to reproofing your waterproof cycling gear, opt for a PFC-free treatment for the greenest option.
Articulated
This is when a fabric is cut along the lines of active use, so that it follows the shape of your arm or curve of your back when in the riding position.
A design of this type enables free movement without the need to be baggy, but may be less suitable for use off the bike.
If you only want one waterproof jacket to do it all, you might have to compromise somewhat in this department.
