How to find a good waterproof cycling jacket to keep you dry in wet weather
Riding in wet weather is no one’s idea of fun, but if you want to make it a little more bearable then a good waterproof cycling jacket is an essential investment. Such a jacket will keep you dry through the foulest weather, making you more likely to head out of the front door whatever the weather, avoiding the dreaded turbo trainer.
What features should I be looking for?
Clearly the most important thing you want to know about any waterproof cycling jacket is how waterproof it is. There are plenty of jackets out there that claim to be “water-resistant” (usually meaning that they have a Durable Water Resistant (DWR) coating applied to the fabric), but these will only keep you dry through showers and relatively light rain. If you want a proper waterproof cycling jacket for real wet weather riding, then you’re going to want something with a little more protection.
The good news is you can get some idea of how waterproof a jacket is by doing a bit of research into any prospective purchase, with an increasing number of manufacturers stating the waterproof rating of their waterproof cycling jackets.
“But what’s a waterproof rating!?” I hear you cry. Well, it’s basically a number, and the higher the better. The number is calculated on the basis that if you put a 1in x 1in square tube over the fabric, how high could you fill the tube water before it started to leak through.
For a good waterproof cycling jacket you’re going to want something with a waterproof rating north of 10,000mm, although there are a number of jackets on the market that claim to offer more than this. However, “claim” is the key word in this sentence, with no central body set up to test these figures, and manufacturers generally doing the testing of their own products.
Ride better in wet weather
It’s also not all about the fabric when it comes to making a waterproof cycling jacket waterproof, with other features playing an important role. Most crucial of all are the seams. You can make a waterproof jacket out of the most waterproof material in the world, but if you then stitch a load of tiny holes in it, it’s not going to do its job very well.
The solution to this is taping the seams, a process which covers the seams with a waterproof material, helping to keep the water out. All of the best waterproof cycling jackets will have this feature, although some will only have taped seams in crucial areas such as the shoulders and back, rather than across the whole jacket.
The other area where water is likely to get in is through the zip. This is particularly the case if you’re riding in the wet in a group, where water is constantly being sprayed up onto your chest by the back wheel of the rider in front. Unsurprisingly the solution is a waterproof zip, which is either taped on the outside or sealed on the inside.
For all that, probably the major factor that distinguishes good waterproof cycling jackets from bad ones (or at least great one from good ones) is breathability. If you’re working hard (as we hope you are!) then you’re going to be building up quite a lot of heat, so a good degree of breathability will allow sweat to escape.
As with waterproofing, it’s possible to put a number to breathability, and again it’s a case of the higher the better. In this case the number refers to the weight (in grams) of water vapour than can pass through a 1m x 1m area of fabric over a 24 hour period. So if you have a jacket with a 20,000 breathability rating, 20,000g of water vapour can escape through the fabric in 24 hours.
Dress properly for your winter riding
Again, for a good waterproof cycling jacket you’re going to want that number to be more than 10,000, but as with the waterproof rating you should always be a sceptic, with manufacturers carrying out all the testing rather than an independent body.
As with any piece of cycling clothing, making sure your waterproof cycling jacket fits properly is a crucial part of the equation. However, it’s not a case of one fit fits all, with different fits being better suited to different types of riding and riders.
If you’re using this jacket for fast rides, maybe heading out for the local chaingang whatever the weather, then you’re going to want a relatively slim-fitting jacket which won’t flap too much in the wind, holding you back with its poor aerodynamic performance. However you don’t want it to be tight, just in case you want to add extra layers underneath in really cold weather.
For everyone else, a slightly looser fit might be more suitable, giving the possibility for bulkier layers underneath and possibly greater comfort too. However you don’t want to go too loose, as this will not only slow you down, but will cause annoying windflap on bustery days, and loose-fitting collar and cuffs could also undermine an otherwise very waterproof cycling jacket.
If you’re riding in changeable conditions, then packability is an important thing to look for in a new waterproof cycling jacket. If the sun comes out after it’s chucked it down for the first two hours of your ride, then you’re going to want something that will stuff down small enough to fit in a rear pocket.
However, in general, waterproof cycling jackets that offer good waterproof protection are generally fairly bulky, so the majority will not pack down that small. So if you want a jacket that will both keep you dry in heavy, persistent rain, and will pack down small enough to fit into a jersey pocket, then expect to pay dearly for it.
Thumb loops are probably the most common extra feature found on many waterproof cycling jackets. These are designed to stop the sleeves from riding up, creating a gap between the cuffs of the jacket and your gloves.
In general, these basically consist of a piece of elastic sewn into the cuff, an unsophisticated design that can quite often pull at the webbing between your thumb and index finger if the sleeves are slightly too short. Better designs incorporate the loop into the cuff, which is more comfortable and looks better too.
To keep your bum dry from wheel spray it’s also worth looking for a waterproof cycling jacket with a long tail (or bumflap). However this isn’t just a case of manufacturers just adding an extra bit of material at the bottom of their jacket, and it’ll need to have some silicon grippers or other devices to prevent it from riding up.
If you’re on a long ride, then you’re also likely to need to access the rear pockets of your jersey in order to get at any energy bars or gels you might have stashed in there. With this in mind, many waterproof cycling jackets will have some sort of opening at the rear, but if your one doesn’t then it’s easy enough just to lift up the tail of the jacket to access your pockets that way.
Finally, it’s also worth looking for a waterproof cycling jacket that has some sort of soft fabric on the insides of the cuffs and collar. This will really help with comfort, feeling much nicer against the skin than the slick, cold material found on the inside of most waterproof cycling jackets.
Our pick of the best waterproof cycling jackets
Sportful Hotpack NoRain jacket
White might not be the most practical option for a waterproof cycling jacket (so thankfully Sportful also makes its Hotpack NoRain jacket in high vis yellow or black), but the performance is still exceptional.
Not only is this jacket exceptionally waterproof and breathable, but Sportful has also nailed the little details with the thumb loops and zip garage.
Planet X Hydrosphere jacket
Planet X might not be the first company you think of when buying some new cycling kit, but that doesn’t mean that Sheffield brand can’t offer clothing that offers just as much value as its bikes.
Case in point is the Hydrosphere jacket, which might lack the finer details of pricier waterproof jackets, but will still keep you dry when the heavens open.
POC Raceday Rain jacket
Yes, £230 is a huge amount of money to blow on a waterproof cycling jacket, but if you can afford it, and you’re riding in the rain a lot, then this POC Raceday Rain jacket is worth the outlay.
Everything about this jacket is superb, with perfect waterproofing, exceptional breathability and fit, and a quality construction which means that it is built to last.
Polaris Hexon jacket
For a penny under £90, the Polaris Hexon waterproof jacket is incredibly hard to fault, even when you compare it to jackets of double the price.
The fit might not be that aero, but this jacket is incredibly waterproof and very breathable, making it a perfect choice if you’re doing hard efforts in bad weather
Castelli Gabba 2 jacket
Ok, so it’s not technically a waterproof jacket, but if you’re looking for a piece of clothing to get you through horrible wet and cold rides, then the Castelli Gabba 2 jacket is a great option.
The water-resistant clothing will keep you dry through showers, but if the rain does get through in heavier downpours, then the insulation will still keep you warm
How much should I pay?
The sky really is the limit when it comes to buying a waterproof cycling jacket, with some options from certain premium bands even nudging close to the £300. However the good news is that you don’t need to spend nearly that much to get a great jacket.
If breathability isn’t a massive issue (for example, if you’re just using the jacket for commuting to and from work) and are willing to do a bit of shopping around, then you can easily pick up a really good waterproof cycling jacket that will keep you nice and dry for less that £50.
For something that will offer better breathability, more features, and probably a closer fit, then you are going to have to spend a little more money. However, there’s no need to go crazy, with the £100-£150 price range offering a whole host of options without getting you in too much trouble with your bank manager.
