Staying warm and dry in is easy with the right outer layer: we put the best waterproof mountain bike jackets to the test. Light shells and storm jackets.
Keep dry and warm with the best waterproof mountain bike jackets. Waterproof jackets fall into two camps – lightweight ones that you can sling on when there’s a sudden down pore and heavier jackets that you’d wear from start to finish on a wet day.
A lightweight jacket usually features a stripped down 2.5layer construction but to make it packable features are also kept to a minimum. It’s still breathable and waterproof but the low weight makes this type of jacket perfect for stuffing in a pocket or carrying in a hydration pack.
In an all-day waterproof, the material is much thicker and hard-wearing, and you’ll get a ton of features such as a double storm flap, permanent hood and lots of pockets, toggle adjusters and vents to manage temperature.
In an ideal world you’d buy one of each but in the real world you may only be able to afford one. The problem both jackets are quite specific to the conditions, so what’s good in a light shower isn’t something you’d want to wear all-day. The reason for this is when riding in one of the all-day jackets you tend to layer accordingly and that often means a long-sleeve base layer underneath, so you can’t just strip down to that once it stops raining. Conversely, a lightweight jacket is not going to offer a lot of warmth, and if you layer up you can get too hot and being soaked in sweat feels exactly the same as being soaked in rain.
Ultimately your choice is between a jacket that you carry with you on a ride or one that keeps you dry at all costs. Only you know which camp you fall into, but either way there’s plenty of choice out there to keep you covered.

Endura MT500 jacket
Great features for heavy winter riding
Pro: Excellent balance of protection and breathability
Con: Nothing serious
Very substantial due to a three-layer Exoshell 60 membrane sandwiched between the Nylon layers but it does have a claimed 60,000 g/m²/24hr breathability rating, which is one of the highest we’ve seen. Waterproofing is rated to 18,000mm, which is not quite as lofty but it’s still very good. Endura claims the ExoShell60 membrane is also PFC free making it somewhat environmentally friendly. To keep out the wet, it’s fully seam-sealed, although you have to be careful to follow the recommended washing advice, because 60-degree can delaminate the tape. There’s extra inner cuffs with thumb loops to stop wind chill and adjustable external cuffs so you can batten down the hatches. An over-the-helmet hood with side adjusters really bring it close in at the sides without restricting vision.
If and when the temperature rises you can vent heat using the pit vents and also supplement those by opening the huge mesh lined front pockets, providing they’re empty of course. A small pocket on the sleeve is handy for car keys and there’s internal mesh compartment perfect for a phone. There are three little niggles – the strap to secure the hood is a bigger than it needs to be, the jacket bunches on the stomach area when you lean forward and the inner storm flap snagged in the zip constantly. In the plus column, overlap is really good at the rear and, for a three-layer jacket, the MT500 is unbelievably breathable. Build quality is excellent, it’s good value and lightweight.
Gore Wear C5 Gore-Tex Trail Hooded jacket
Compact and incredibly lightweight package
The C5 Trail Hooded features a small hood, which works best when it’s under the helmet. Two elasticated laces on the side let you get it snug against the face so it doesn’t flap around and you also can’t see it out of the corner of your eye when riding. There’s also a neat little closure to store the hood when not in use. Internally all the seams are fully taped and, to keep water at bay, there is an internal storm flap on the zip and a high collar. Unfortunately, due to the uneven seam edge we managed to snag the storm flap in the zip on almost every ride. We also broke one of the leashes out of the waist when tightening it for the first time.
This jacket doesn’t have vents but to be honest they’re hardly necessary as it breaths so well. There wasn’t a hint of internal condensation and the only dampness was at the rear, where splatter would eventually work its way between the jacket and trouser. Gore doesn’t go a bundle on carrying capacity with just two small side pockets and a napoleon pocket for a phone and keys. We like the fact that its minimal, it’s stripped back with everything you need. It comes second best this time because the Endura just edges it on breathability and value.
Altura Mayhem 2
A very capable all-rounder
Pro: Good value
Con: Generous sizing
The jacket is built using the company’s three-layer Stormshield material, which is rated 15k for waterproofness and breathability. All the seams are fully taped to stop water ingress and there’s a full-length waterproof zip as well as an internal storm flap for added security. It’s fit is snug at the neck with a fleece-lined collar and integrated zip gutter. Like the Alpine Star’s Tahoe the Mayhem 2 has reinforced rip stop sections over the sleeves to reduce crash damage. To keep the rain off, there’s a small storm peak on the front of the hood but the single toggle adjusters are too long and it can’t decide whether it works over or under a helmet – it’s too small for the former, too loose for the latter. Once out on the wilds the Mayhem 2 proved fully waterproof and the high neck stop the worst of the spray. There were a few patches where the DWR hadn’t quite penetrated the material but water pooled off the surface reasonably well.
The Mayhem 2 is a decent allrounder but we’d like to see some bigger vents and it could also do with a bit streamlining, even with several base layers it’s really billowy in the chest and arms but oddly short in the body. Overall a great value, hard wearing waterproof but let down by the hood and odd sizing.
Endura MTR Shell jacket
One of the lightest jackets that still protects
Pro: Minimalist yet adaptable
Con: Hood not stowable
Endura’s MTR Shell was the test winner in our lightweight waterproof jacket test a year ago and 12months on it remains relatively unchanged. It’s still constructed from Endura’s in house Exoshell 40 fabric, which is rated to 20k for waterproofness and a whopping 40k for breathability. It’s pretty minimal jacket with no pockets, vents and only stretchy elastic rather than toggles at the hems. There’s silicone gripper on the bottom to stop the jacket riding and micro-printing on the shoulders to reduce strap abrasion. The hood clips on via press studs, so can be removed easily if you don’t want it flapping about, we’d just like to see a small storage pocket to stash it in. With elastic round the front, the hood sits okay over the helmet but it’s less comfortable underneath.
With its lightweight design the MTR Shell doesn’t feel like it’s going to cope with more than a light shower but the waterproofing is excellent with the water droplets all coalescing together and pooling on the surface fabric. It’s also incredibly breathable so we never felt clammy or too hot riding hard in this shell. At 216g, the MTR Shell is lightweight but with handy packing strap, housed in the collar, it can be packed down in seconds. This is the perfect jacket for taking with you on a ride but it’s also substantial enough to be worn all-day. Lightweight, versatile and surprisingly good value – easily our test winner!
Gore Wear C3 Gore-Tex Paclite hooded jacket
Truly excellent lightweight jacket
Pro: Pack away or wear all day, it’s great
Con: Takes a while to dry out
Usually Gore Bike Wear jackets are some of the most expensive we test but the C3 Gore-Tex Paclite is mid-pack price wise but still features a proper Gore-Tex fabric and the company’s excellent attention to detail. The C3 Paclite isn’t the lightest jacket on test but it is minimal with slim adjustable cuffs, tiny draw-string toggles and a compact hood. This is fixed permanently to the jacket, so will flap around if you choose not to use it but it can be cinched down really tight under the helmet. We did try it over the top but on most modern trail lids it only reached half way.
All the seams are fully taped and, to keep water at bay, there are storm flaps on the zip and a high collar, which tucks neatly under the chin. To stop irritation, you get a semi-fleece collar and a zip garage. There are no vents but to be honest they’re hardly necessary with a jacket that breaths this well. With its cut back design, there’s only a single Napoleon pocket on the chest but this doubles as a stow-away pocket, it even comes with a double-sided zip. Gore has recently switched to a PFCec Free DWR coating on all of its garments and while this pools water reasonably well, there were some patchy areas on the C3 Paclite. This doesn’t affect the waterproofness but the jacket did take longer to dry out. The C3 Paclite is in a select group – it packs down small but it has enough protection so you can easily wear it all day.
Madison DTE Storm jacket
One to save you in the depths of winter
Pro: Great for when it’s THAT bad out there
Con: For colder temperatures only
At over half a kilo, the Madison DTE Storm is definitely a jacket you’d wear on a cold wet ride rather than one you’d pull out when there’s a rain shower. It’s constructed from a heavy duty, three-layer fabric that is fully seam sealed and features a high-wicking inner layer and some large mesh panelling to absorb moisture. The fleecy collar is quite deep but we found it gapes open and in heavy downpours water can get in. The hood on the DTE Storm is biggest on test and easily fits over a full-sized trail helmet but with the dual adjustment you can cinch it down tight and run it underneath. There’s a storage strap to secure the hood but rolled-up this just feels bulky against the neck, so we just left it hanging loose when we weren’t using it..
Of all the jackets the DTE Strom had the best surface finish –water seemed to fly off the out layer. It’s also one of the warmest jackets too, which is great for colder conditions but in milder weather we found we had to layer up carefully and make full use of the large 12-inch pit vents under the arms. The two side pockets and a central chest pocket can also be opened to act as secondary vents. The type of waterproof you wear is condition dependent and if you’re up on the moors or high hills on a cold wet day the DTE Storm is the jacket we’d choose.
Scott MTN Stretch Hybrid 30 jacket
One for the pocket fans
Pro: Good value for features and high tech fabrics
Con: Not technically a waterproof
As the name suggests, Scott’s Trail MTN stretch hybrid 30 jacket is a combination of two materials – a four way stretch DUROxpand material used for the bulk of the jacket and DRYOsphere 3L on the lower back, shoulders and hood. These are the areas where you get spray and constant soaking, hence the waterproof material. The four way stretch material does get a DWR treatment, so pools water pretty well and it feels great against bare skin, such as when wearing a short sleeve base layer, but it does tend to pick up dirt and water does eventually soak through. The MTN 30 does have some really smart detailing such as a microclosures on the cuffs, a plush fleece collar, front storm flap and a zip garage. The permanent hood is designed to go under a helmet and comes with a bonded brim and neat adjustment, fastening round the head like a bandana.
Storage capacity with the MTN 30 is off the chart with two gigantic front pockets, one of them features a security pocket to store your essentials, and two massive internal sleeves, which can easily swallow an OS Map and a soft water bottle. With only strategic waterproof panels the MTN 30 doesn’t offer the same sort of protection as a full-on waterproof but if only showers are forecast it’s more than capable. It’s more a winter jacket than a waterproof but it’s comfortable, sleek fitting and great value.
A note about e-bike apparel
Usually when testing the warmth and breathability of waterproof jackets we use conventional trail bikes because you can really feel how the temperature increase by just cranking hard up hill. However, this year we’ve been out a few times on the e-bikes and things are a lot different when you’re assisted – you usually don’t generate as much heat when you’re climbing and you’re going faster, so wind chill can have a greater effect. When that happens, you don’t want the jacket to breath that well and you actually want to retain some heat. We not suggesting there’s a new category of e-bike specific waterproof, although we wouldn’t put it past companies to do this, but if you’re riding an e-bike full time you may need to tailor your wardrobe accordingly. The jackets we recommend for e-bike riders are the Madison DTE Storm and Altura Mayhem. These jackets are also good for all-day riding because you can really shield yourself from the elements if you venture up onto the high hills.
Spot the best waterproof mountain bike jackets
Most quality waterproof jackets are built from a laminate fabric, which consists of a waterproof and breathable membrane sandwiched between nylon layers. The membrane is the bit that keeps you dry and Gore-Tex is the most common but dozens of jacket manufacturers make their own version.
All waterproof fabrics are rated for waterproofness (you’ll usually find this on the label) and anything over 10,000mm is pretty watertight in normal conditions. Breathability is also rated – look for the MVTR (Moisture Vapour Transmission Rate). A figure above or around 20,000g/m²/24hr is pretty good.
Manufacturers describe their jackets as having two or three layers but what does this mean? A two-layer fabric is made up of an outer face fabric bonded to the waterproof membrane, usually with a mesh liner hanging inside. On a 2.5 layer, the mesh liner is replaced with a micro (or half) layer, which is either bonded or printed. On a three-layer jacket you still get a membrane but it’s sandwiched between two tougher nylon layers.
Riding hard generates heat, and then sweat, so if you want to expel that you’ll need some form of venting. Look for zipped vents under the arm pits or over the chest area and also exhaust venting, simple slits over the shoulder blades. Mesh-lined pockets that you can just open to let air in also help with condensation build up.
Adjustable cuffs, collars and hems stop water getting in but also help regulate airflow the inside of the jacket. They do add weight, so on some lightweight jackets they’re eliminated in favour of elasticated seams.
Some zips are waterproof, some are not. If it’s the latter you will need a storm flap to stop the water passing through. Also look for an easy to pull toggle and a zip gutter (garage) to stop the end of the zip cutting into your neck.
A hood prevents water running down your neck and keeps heat in. Nine of the jackets here have the, and most designed to fit underneath the helmet, a few over the top and one that can do both. The best hoods have dual adjustment, so you can get them tight against your bonce.
These are handy for keys, phone and tools. Look for a waterproof napoleon or chest pocket for your dosh, large internal pockets for a map or bottle and a zipped rear pocket to stash the jacket in when not in use.
