A waterproof jacket is your first line of defence when the forecast turns. It blocks rain, cuts wind and helps hold warmth when temperatures drop.

In exposed terrain, that’s crucial.

Key benefits:

• Protection from rain and wind

• Keeps base layers dry

• Temperature regulation across changing conditions

A dependable waterproof and windproof jacket keeps you comfortable when the weather can’t make up its mind.

Choose well, and you stay out longer. Choose poorly, and your trip could be cut short.

Not all waterproof jackets are built for the same job. Some handle short showers. Others are made for multi-day trips in exposed country.

Here’s what to focus on.

Breathable Fabric Climbing and hiking generates heat. Breathable fabric lets moisture escape so you don’t get soaked from the inside.

Seam-sealed construction Water pushes through stitching first. Fully sealed seams stop leaks at the weakest points.

Adjustable hoods and cuffs A secure hood and tight cuffs stop wind-driven rain getting in. Simple, yet effective.

Other details that matter:

• Room to layer underneath

• Freedom through the shoulders

• Pockets you can access with cold hands

The best waterproof jacket should feel easy to move in on long hikes or while working, offering protection without feeling restrictive.

Waterproof ratings help you match your jacket to the conditions.

They’re measured using a hydrostatic head test, which checks how high a column of water (in millimetres) the fabric can withstand before leaking. A 10,000mm rating means resistance to a 10 metre column of water pressure. A 20,000mm rating equals 20 metres.

What that really means is 10,000mm will handle most conditions, while 20,000mm is serious protection — more sustained rain pressure than most people will ever face.

To learn more about how waterproof ratings work on clothing, check out our comprehensive guide.

10,000mm rated rain jacket

A 10,000mm rated rain jacket is suited to moderate rain and general outdoor use. It handles steady showers and everyday conditions well.

Good for:

• Day hikes

• Farm or work use

• Around-town wear

20,000mm rated rain jacket

A 20,000mm rated rain jacket is built for heavier rain and more exposed environments. It’s better suited to tramping, hunting, and multi-day trips where weather can set in.

If you’re regularly out in harsh conditions, stepping up to this rating makes sense.

Warm waterproof jacket

A warm waterproof jacket combines insulation with weather protection, such as a waterproof puffer jacket designed for cold, wet conditions. It’s ideal for those days when the rain sets in and the temperature drops with it.

It’s

ideal when you need:

• Added warmth in winter and shoulder seasons

• Less layering bulk

• Protection from both rain and low temperatures

For cold, wet environments, a warm waterproof jacket keeps things simple and effective. Throw it over a merino base layer, and you’re good to go.

Changeable weather is tough on gear. These options are built to handle it.

• Bushbuck Alpine Waterproof Jacket – Lightweight, 4-way stretch, 20,000mm rating. Designed for movement in demanding terrain. A strong choice if you want a lightweight waterproof jacket with serious protection.

• Bushbuck Typhoon Waterproof Jacket – 20,000mm and our most waterproof jacket yet. Extra length for maximum coverage in driving rain. Built as a true waterproof and windproof jacket for harsh conditions.

• Bushbuck Igloo Waterproof Canvas Puffer Jacket – Added warmth with full waterproof protection rated to 10,000mm. 800 loft duck down insulation. Durable canvas outer suited to tough environments. A practical waterproof puffer jacket that delivers insulation and weather resistance.

• Bushbuck Defender Waterproof Jacket – 10,000mm rated with the toughness of Oxford nylon. Popular for workwear and demanding jobs where durability matters.

Look at waterproof rating, durability, and real-world performance first.

Start with your environment.

Ask yourself:

• Will I be out in exposed backcountry where weather can change quickly?

• Am I heading into alpine or winter conditions where I’ll need a warm waterproof jacket?

• Will I face strong wind on ridgelines or open country? If so, a waterproof and windproof jacket is essential.

• Do I need a lightweight waterproof jacket for long, multi-day trips?

• Will I be using this for work where I need a more durable outer fabric that can handle wear and tear?

Then check the build:

• Fabric that’s breathable

• Seam sealing quality

• Waterproof rating suited to your conditions

• Fit that layers properly over base and mid layers

The best waterproof jacket is the one matched to your terrain, not just the highest number on a tag.

Even the best waterproof jacket needs proper care.

To keep it performing:

• Follow washing instructions closely

• Avoid fabric softeners

• Reapply waterproof treatments when needed

• Repair small damage early

Good care keeps your waterproof jacket reliable season after season.

In changeable conditions, a dependable waterproof jacket is essential kit.

Understand what the waterproof rating actually means. Match it to your environment. Decide whether you need a lightweight waterproof jacket, a warm waterproof jacket, or a higher-rated shell built for serious downpours.

Choose for the conditions you actually face. That’s how you stay dry and comfortable when it matters.

How can you tell if a jacket is waterproof? Check the waterproof rating, usually measured in millimetres (mm). A true waterproof jacket will list a rating such as 10,000mm or 20,000mm and have sealed seams. 

Should I buy a waterproof or water resistant jacket for hiking? For hiking in changeable or exposed conditions, a waterproof jacket is the safer choice. Water resistant jackets handle light showers but can wet out in sustained rain. In remote terrain, full waterproof protection gives better long-term comfort and safety.

If a jacket is waterproof does that mean it is also windproof? Most waterproof jackets also block wind because the same membrane that stops water prevents wind penetration. However, it’s still worth confirming it’s described as a waterproof and windproof jacket, especially for exposed ridgelines or coastal conditions.

What should you consider when buying a rain jacket? Look at waterproof rating, seam sealing, how breathable it is, fit, and intended use. A rain jacket for light use may not suit backcountry trips. Match the rating and build quality to your environment, especially if you’re heading into remote or changeable conditions.

What are the various waterproof ratings? Waterproof ratings are measured in millimetres (mm) using hydrostatic head testing. A 10,000mm rating means the fabric can withstand a 10 metre column of water pressure. A 20,000mm rating withstands a 20 metre column. Higher numbers generally mean stronger resistance to prolonged or high-pressure rain.

Is a warm waterproof jacket better than layering? A warm waterproof jacket simplifies your system by combining insulation and rain protection. It works well in cold, wet conditions where you won’t be removing layers often. For high-output hiking, separate layers may offer more flexibility and temperature control.

What makes the best waterproof jacket for harsh conditions? The best waterproof jacket for harsh conditions has a strong waterproof rating, sealed seams, good wind protection, and durable fabric. In fast-changing weather, reliable performance matters more than extra features.
