How to Choose the Right Waterproof Jacket
We’ve grouped our waterproof jackets into three categories - Everyday, Light Trail, and Outdoor Performance to help you pick the right option based on your activity, whether you need simple rain protection for daily wear or a high-tech shell for rugged mountain conditions.
Remember, you don’t always need the most advanced or waterproof jacket; choosing one that matches your specific use will keep you comfortable and dry without extra bulk or cost.
Which Waterproof Jacket is Right for You?
Here are general sections to give you an idea of what to consider when picking your jacket. Your needs might fall into multiple categories or there might be certain features you value over others. If you need help with selecting a jacket please get in touch with us and we will be able to point you in the right direction with more specific recommendations.
Everyday
A great choice if you’re looking for reliable, no-fuss protection from light to moderate rain - perfect for taking you from commuting, to walking the dog, to the Saturday trail walk with the family.
The waterproof jackets in this category usually feature a 2-layer construction, which keeps costs down while still offering solid waterproofing and a comfortable feel thanks to the soft inner lining.
They're designed with daily life in mind, so they're easy to wear, often come with practical features like adjustable hoods and zip pockets, and are ideal for casual outdoor use. Just keep in mind that they can be a bit heavier and less breathable as more technical jackets as they are not intended for high levels of physical exertion.
What you might want to look out for:
- Comfortable or relaxed fit
- Adjustable hood, hem or cuffs
- Practical pockets
- Reflective details for road walking
Light Trail
If you're heading out on the trails for a few hours, like a half-day hike, you'll want a jacket that keeps you dry without slowing you down. Both 2-layer and 2.5-layer jackets work well.
2-layer jackets offer a bit more comfort and durability, which is great for steady-paced hikes where weight isn’t your biggest concern.
On the other hand, if moving fast, a 2.5-layer jacket can be lighter, pack down smaller, and won’t feel bulky when you’re on the go. Because 2.5-layer jackets don’t have a full lining inside, unlike 2-layer jackets, remember to wear wicking base layers underneath to prevent feeling clammy when you start to sweat.
If you’re doing a high energy activity, breathability can be key, along with ventilation like underarm zips and it might be worth sacrificing a little on the level of waterproofing.
Overall, if you’re after something lightweight, weatherproof or easy to stash when the sun comes back out, this category is built for you.
What you might want to look out for:
- Lightweight
- Packable
- Adjustable
- Taped seams
- Underarm zips - for extra airflow and increased ventilation
Outdoor Performance
This category is built for tougher conditions, seasoned mountain hikers, professionals - think of anyone spending long days outdoors in potentially harsh, changeable weather. You’ll find a mix of 2-layer and 3-layer waterproof jackets.
3-layer designs offer top-tier performance thanks to their durable, bonded construction and advanced fabrics like Gore-Tex and other high-spec waterproof membranes. These jackets provide a high level of waterproofing and breathability, built to withstand heavy rain, snow, and strong winds. Expect features like waterproof zips, helmet-compatible hoods, underarm zips, and reinforced panels for use with backpacks or climbing gear.
2-layer jackets in this section also offer great protection and comfort, often with a more accessible price tag. While they’re heavier and more technical than everyday options, these jackets are made for when the weather’s at its worst and you need gear that won’t let you down.
What you might want to look out for:
- Durability
- High waterproofing level
- Adjustability - hoods, hem, cuffs
- Underarm zips - increase ventilation
- Waterproof zips
- Reinforced fabric in certain areas
- RECCO
The Techy Bit
To help you choose the right jacket, it’s useful to know a bit about the tech. Understanding things like waterproof ratings, breathability, and seam taping will give you a clearer idea of why certain jackets are designed for everyday use, while others are built for tougher mountain conditions.
How waterproof do I need my jacket to be?
This depends on what activity you are doing and how long you could potentially be out in the rain.
The waterproofing level on a jacket you'll only be using for the school run or walking the dog won't need to be as high as on a jacket you're going to spend 6 hours in, up a mountain in the lashing rain.
How is waterproofing measured?
Hydrostatic Head (HH) is the measurement of how waterproof a fabric is. It tells you how much water pressure a fabric can handle before it starts to let water through. It is expressed in millimetres (e.g. 10,000mm). The higher the mm rating the more waterproof a garment is. The minimum level for a fabric to be considered waterproof in Ireland/UK is 1500mm.
How breathable will my waterproof jacket be?
Hikers in Ireland often face mild, damp conditions - mist, drizzle, or rain - where it's too warm for a waterproof jacket, especially during activity, yet too wet to go without one. Jackets can feel clammy inside, but that’s not a failure in breathability; it might be your body overheating and moisture needing more time to escape. Try the same jacket on a cold, wet day, and you’ll notice how well it actually breathes.
How is breathability measured?
Breathability of your waterproofs is important in high exertion activities like intense hikes or trail running. If your jacket didn’t let sweat, in the form of gaseous vapour, out you’d be drenched from the inside. Moisture Vapour Transmission Rate (MVTR) measures how breathable a fabric is. It’s normally expressed in terms of how many grams (g) of the gaseous water vapor (your sweat) can pass through a square meter (m2) of the fabric from the inside to the outside in a 24 hour period e.g. 20,000g/m². The larger the number, the more breathable the fabric.
How can I maximise the breathability of my waterproof jacket?
- Wear appropriate wicking layers under your jacket to prevent overheating
- Find the right balance between your jacket's level of waterproofing and breathability - this will depend on your activity and exertion level as sometimes higher waterproofing can result in lower breathability
What is DWR?
DWR or Durable Water Repellent is a treatment applied to a fabric which keeps it from becoming saturated with water and adding weight. DWR causes water to bead-up and roll off the fabric. This helps maintain the breathability of your waterproof jacket or trousers because the water doesn’t sit on the membrane/coating.
Do I need to reapply DWR?
Yes. Over time, DWR wears off and needs to be refreshed - usually by washing the garment with a specialised treatment like Grangers.
What’s the difference between waterproof and water resistant?
Waterproof jackets - Use a membrane or inner coating along with seam-sealing/taping, storm guards or waterproof zips to ensure rain cannot get in. Don’t forget the hood and sleeves! Waterproof jackets will usually give you a hydrostatic head rating or information on the waterproof lining, coating or features. Waterproof jackets are windproof too.
Sealed/taped seams - Covers the tiny holes made by the needle in the sewing process so they don’t leak, either fully or in high-exposure areas. Without seam sealing you’ll get wet even with the best waterproof/breathable fabric.
Storm guards - Extra waterproof fabric covering zippers
Water resistant jackets - Only have a DWR coating on the face fabric and so are only good for light showers, not for more intense weather.
What are the layers in waterproof garments?
- Face fabric - Not waterproof. Protects membrane or coating as well as providing the stylish look of the garment. Face fabric is treated with a solution called DWR (Durable Water Repellent) so it doesn't soak up the water.
- Membrane - Laminate or liquid coating that keeps the garment waterproof by preventing water from penetrating the inside of the jacket and allowing vapour (sweat) to escape.
- Backer/lining - Scrim or mesh is bonded to the inner surface for comfort and protection.
What is a 3 Layer (3L) waterproof jacket?
Face fabric, membrane and backer are bonded together. Usually used in high spec garments as it allows the use of rugged face fabrics without creating excessive bulk and weight.
What is a 2 Layer (2L) waterproof jacket?
Face fabric and membrane are bonded together and finished with a loose mesh or fabric lining. This type of construction creates a bulkier garment but the mesh liner prevents the sensation of excessive condensation build up from sweat.
What is a 2.5 Layer (2.5L) waterproof jacket?
Face fabric and membrane are bonded together but instead of fabric liner there is a thin protective coating or printed layer on the inner surface to protect the membrane. This reduces weight and bulk making the garment super lightweight and packable. Wicking layers underneath are highly recommended to avoid feeling clammy.
What are other features of waterproof garments?
These can vary depending on your needs or activity:
- Waterproof zippers - YKK Aquaguard/Vislon. Please note - Waterproof pocket zippers are never guaranteed fully waterproof. Condensation from body heat can build up in the pocket or water can get in if the zip is not closed properly
- Reinforced waterproofing - In pressure points like knees, shoulders, hips
- Reinforced face fabric - In pressure points like knees, shoulders, hips
- Hood - Is it adjustable, is it helmet compatible or does it have a stiffened peak?
- Underarm zips - For extra airflow and increased ventilation
- Pockets - Extra pockets in the chest, hand or internally
- Adjustability - hood, hem, cuffs

Waterproof Garment Care
Caring for your waterproof garment helps maintain its water-repellent finish and breathability, ensuring it performs as designed. Over time, dirt and oils can clog the fabric’s pores, reducing its effectiveness. Regular cleaning and reproofing keep the garment performing well and extend its lifespan - saving you money and reducing waste.
How to Wash
Always follow the label care instructions on your waterproof garment, however, here is a general step-by-step you can follow for most waterproof garments:
- Close all zips and fastenings
- Machine wash on a full length gentle cycle at 30 degrees
- Use a waterproof specific detergent like Grangers Performance Wash or a non-biological detergent if necessary
- Do not use any fabric softeners or bleach
- Tumble dry on low to reactivate DWR coating
- Do not iron
- Do not dry clean
