Cycling Rain Jackets Buying Guide
1. Types of Fabrics Used
The most important consideration when you’re deciding on a waterproof cycling jacket is the type of fabric. They are either made from laminate fabrics or they’re treated with Durable Water Repellant or DWR.
Laminated Jackets
These are multi-layered. The inner layer is porous to release moisture from sweating, but the pores are too small to allow water droplets from rain to come through.
The outer layer typically has a DWR treatment.
Durable Water Repellant
DWR treatments force water to retain its surface tension, so the water beads and slides off instead of soaking through the fabric.
The fabric stays breathable because the treatment doesn’t fill gaps in the fabric; it makes the fabric fibers bond.
2. Waterproofing Ratings
Not all waterproof jackets are created equal and they all perform differently.
Clothing manufacturers (not all of them) express the waterproofing capabilities in terms of mm. Let’s imagine you put a square 1″ x 1″ tube over a piece of waterproof fabric, you’ll need to fill the tube up to 10,000mm (10 meters) in height before water starts leaking through.
The higher the number, the better the waterproofing capabilities.
According to industry standards, here are the waterproof ratings explained.
- Less than 10,000mm. Minimal protection for activities like running and hiking in intermittent light rain and snow.
- 10,000 – 15,000mm. Medium protection for activities like hiking and skiing in moderate rain, snow, and wind.
- 15,000 – 20,000mm. Excellent protection for most activities in moderate rain, snow, and wind, with intermittent heavy rain and snow.
- More than 20,000mm. Extreme protection for persistent heavy rain, heavy snow, high winds, and very wet environments. Ideal for activities like mountaineering, ice climbing, backcountry skiing, and kayaking.
3. Breathability Ratings
No one wants to be covered in sweat while they cycle. Waterproof jackets may have an inner wicking layer as well as vents to help keep you dry.
They typically come in 2.5 to 3 layers and may have additional ventilation in areas where you’re most likely to sweat, such as under the arms.
Some manufacturers (again, not all) do provide breathability ratings.
It’s a number expressed in terms of how many grams of water vapor can pass through a square meter of fabric in 24 hours.
4. Size and Fit
The type of fit you need depends on the type of cycling you do.
If you’re looking for speed, you’ll want a more aerodynamic jacket with a slimmer and snug fit.
If you’re spending long days on the road, you might want something with a looser fit so you can wear layers underneath.
Some also include details like a longer tail and thumb loops, which are great extra features to have.
5. Packability
If you ride in unpredictable weather conditions, or if you’re expecting changeable weather during the ride, you may want a jacket that can be easily packed up and fit into the back pockets.
Some can be folded down to be quite small and have their own little pouch, while others are bulkier and might not be as easy to store when the weather changes.
Frequently Asked Questions
1. How waterproof should my cycling rain jacket be?
I’d recommend looking for those that are rated between 10,000 to 20,000mm.
With these, you’re looking at medium to excellent protection from heavy downpours when you’re out riding.
Having said that, it’s also important to have excellent seam taping to ensure water doesn’t seep through the tiny holes made by needles during the sewing process.
Otherwise, the highest waterproof-rated jacket wouldn’t be able to keep you dry.
2. How breathable should my cycling jacket be?
A layer of warm, moist air sits between the jacket’s inner layers and your underlayers.
A very breathable cycling jacket is not ideal especially in cold weather as it could the warm air to leave your body, leading to heat loss causing you to feel cold.
At the same time, it should also retain some of this warm air to keep you warm from the inside.
Hence, there is a very fine balance between breathability and keeping warm. Too much of either is not ideal.
You’ll want to look for a jacket rated around 10,000 to 15,000g/m2/24 hours for cycling. The larger the number, the more breathable the fabric is.
3. How can the rain jacket both waterproof and breathable at the same time?
A typical waterproof jacket is made up of 3 layers.
- Outer layer, called the Face Fabric, protects the inner layers and provides stylish looks. It’s not waterproof but is treated with a DWR (Durable Water Repellent) solution not to hold up water on the surface.
- Middle layer is called the membrane. Its job is to keep the water out completely. What’s unique about this layer is that it has holes that are too tiny to let water in a while, having holes that are large enough for water vapor to escape, keeping you dry from the inside.
- Innermost layer, the mesh liner, provides comfort while also providing sweat-wicking capabilities.
4. What is DWR and how does it work?
DWR stands for Durable Water Repellent.
It’s a chemical treatment used on most outdoor clothing to make them waterproof. With DWR treatment, causes water to bead up and roll off the fabric which would otherwise add weight causing discomfort.
Take note that the DWR treatment from the factory can wear off over time due to exposure to outdoor elements, oil, and dirt. This causes the rain jacket to be no longer waterproof.
However, this can be easily treated at home by yourself to reactivate the DWR properties. You can buy aftermarket DWR sprays like Grangers and Nikwax and spray them on the jacket after washing.
Alternatively, you can tumble dry them in a warm, gentle cycle after washing.

5. What is GoreTex?
GoreTex is a waterproof and breathable fabric found in outdoor activity clothing invented by Gore. It’s invented in 1969 and a registered trademark of W.L. Gore and Associates.
Gore-Tex fabrics have the capabilities to repel water drops while allowing water vapor to exit.
Since its inception, there are now various variations of GoreTex such as GORE-TEX® Pro, GORE-TEX® Active, and just the standard GORE-TEX®.
You’ll notice that most premium waterproof cycling jackets come with Gore-Tex fabrics, while low to mid-range jackets usually use the manufacturer’s own proprietary waterproof fabrics.
