Choosing your first proper rain gear can feel overwhelming. Walk into any outdoor store and you'll find walls of jackets, ponchos, and rain pants with confusing specifications and price tags ranging from twenty dollars to several hundred. How do you know what you actually need?
This guide cuts through the confusion and helps you understand the fundamentals of rain protection. By the end, you'll know exactly what features matter for your specific activities and how to make an informed purchase that keeps you dry without breaking the bank.
Understanding the Basics: What Makes Gear "Waterproof"?
Before diving into specific products, it helps to understand what waterproofing actually means. There's a significant difference between "water-resistant" and "waterproof," and knowing this distinction will save you from disappointment.
Water-Resistant vs Waterproof
Water-resistant items can handle light moisture—think morning dew or a brief drizzle—but will eventually let water through under sustained exposure. Many casual jackets and fashion ponchos fall into this category.
Waterproof items are designed to keep water out even under pressure and prolonged exposure. This is what you need for serious outdoor activities. Waterproof gear achieves this through either coated fabrics or laminated membranes.
In Australia, the Consumer Law requires accurate claims, so if something says "waterproof" it should genuinely resist water penetration. However, "water-resistant" is a vaguer claim with no specific standard, so always check reviews and specifications.
How Waterproof Ratings Work
Waterproof ratings are expressed in millimetres (mm) and represent how much water pressure a fabric can withstand before leaking. The test involves a column of water pressing against the fabric—hence the term "hydrostatic head."
- 1,500mm: Light rain, minimal pressure. Suitable for casual use.
- 3,000-5,000mm: Moderate rain, some pressure from sitting or kneeling.
- 10,000mm+: Heavy rain, sustained use, pack straps pressing on shoulders.
- 20,000mm+: Extreme conditions, professional-grade protection.
For most Australian conditions, gear rated 5,000mm or higher handles everyday hiking and camping needs effectively.
Ponchos vs Rain Jackets: Which Is Right for You?
The first major decision is choosing between a poncho and a rain jacket. Each has distinct advantages and disadvantages depending on your activities.
When to Choose a Poncho
Ponchos excel when:
- You're hiking with a backpack—ponchos can cover both you and your pack
- Ventilation is a priority—the open sides provide excellent airflow
- Weight and packability matter—ponchos are typically lighter than jackets
- You need versatility—many ponchos double as tarps or ground sheets
- Budget is limited—quality ponchos often cost less than comparable jackets
When to Choose a Rain Jacket
Rain jackets work better when:
- You're in windy conditions—jackets seal against the body better
- You need freedom of movement—climbing, scrambling, or technical terrain
- You want a sleeker look for urban or casual use
- You'll wear it for cycling or activities where a poncho could catch wind
For bushwalking and general hiking in Australia, ponchos often make more sense than jackets. They handle our warm rain better (more ventilation), cover backpacks effectively, and cost less. Save rain jackets for alpine conditions or when you need a form-fitting option.
Key Features to Consider
Once you've decided on a general type, these features help you narrow down specific products.
Hood Design
A good hood makes an enormous difference in real-world use. Look for:
- Volume adjustment—toggles or drawstrings that let you tighten around your face
- A brim or peak that sheds water away from your face
- Compatibility with helmets if you'll cycle or climb
- Ability to turn your head without the hood staying fixed
Seam Construction
Waterproof fabric means nothing if water leaks through the seams. Quality gear features:
- Fully taped seams: Waterproof tape covers all stitching on the inside
- Critically taped seams: Only the most exposed seams are taped (budget option)
- Welded seams: No stitching at all—the material is bonded together
For serious rain protection, fully taped or welded seams are worth the extra cost.
Ventilation
The most waterproof garment in the world becomes useless if you're soaked in sweat from the inside. Look for:
- Pit zips (underarm vents) on jackets
- Open sides or mesh panels on ponchos
- Two-way zippers for additional airflow options
- Breathable fabrics with high MVTR ratings (more on this in our breathability guide)
Weight and Packability
Rain gear you leave at home because it's too heavy or bulky provides no protection. Consider:
- Will this fit comfortably in your day pack?
- Does it stuff into its own pocket for easy access?
- Is the weight reasonable for your typical activity level?
Ultralight options (under 200g) exist but typically sacrifice durability. For most users, 200-400g strikes a good balance between weight and robustness.
Materials: What Should Your Gear Be Made From?
Understanding materials helps you evaluate quality and predict performance.
Nylon vs Polyester
Both are common in rain gear with slightly different characteristics:
- Nylon: Generally stronger weight-for-weight, but absorbs small amounts of water. Premium choice for durability.
- Polyester: Doesn't absorb water, resists UV degradation better. Good all-rounder, often more affordable.
For most users, both work excellently. Focus on construction quality rather than agonising over this choice.
Fabric Deniers
Denier (D) measures thread thickness. Higher numbers mean heavier but more durable fabric:
- 10-15D: Ultralight, excellent packability, but prone to tears
- 20-40D: Good balance of weight and durability for most users
- 50D+: Heavy-duty, resists abrasion, heavier to carry
Ripstop fabrics feature reinforcing threads in a grid pattern that prevent small tears from spreading. Even in lightweight deniers, ripstop construction adds significant durability. Look for this if you'll be around bushes, rocks, or other tear hazards.
Setting Your Budget
Rain gear spans a wide price range, and more expensive doesn't always mean better for your needs.
Entry Level ($20-50)
Budget options work for occasional use and fair-weather camping. Expect:
- Basic waterproofing (2,000-5,000mm)
- Limited breathability
- Simpler construction
- Shorter lifespan with regular use
Good for emergency backup, car kits, or testing whether you enjoy an activity before investing more.
Mid-Range ($50-150)
The sweet spot for most users. You'll find:
- Reliable waterproofing (5,000-10,000mm)
- Reasonable breathability
- Quality construction with taped seams
- Good durability for regular weekend use
Recommended for anyone who hikes or camps regularly but doesn't need professional-grade equipment.
Premium ($150+)
Worth considering for frequent users or demanding conditions:
- Excellent waterproofing and breathability
- Advanced materials like Gore-Tex
- Superior construction and durability
- Better warranty and support
Making Your First Purchase
Armed with this knowledge, follow these steps to find your ideal rain gear:
- Define your primary activity: Hiking? Commuting? Festivals?
- Set a realistic budget: More than you'd spend on a t-shirt, but not mortgage-threatening
- Identify must-have features: Pack coverage? High breathability? Ultralight?
- Research options: Read reviews from people with similar needs
- Check fit if possible: Try on with the layers you'll wear underneath
Don't agonise too long—even a budget poncho protects better than nothing, and your preferences will become clearer with experience. You can always upgrade later once you know exactly what you want.
