Ultimate Guide to Choosing a Waterproof & Breathable Jacket

When facing unpredictable weather, a jacket that balances waterproofing and breathability is essential for outdoor enthusiasts. But with endless technical terms like "hydrostatic head" and "moisture-wicking membrane," How do you choose? This guide breaks down the science behind waterproof-breathable jackets, shares expert tips for selection, and highlights TOREAD’s cutting-edge solutions to keep you dry and comfortable.

Part 1: Understanding Waterproof vs. Breathable

1. Waterproofing

   Huichen are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

   • Key Metric: Hydrostatic Head (HH) rating (e.g., 10,000mm). Higher HH = better resistance to water pressure.
   • Limitation: Pure waterproof materials (e.g., rubber) trap sweat, leading to condensation inside.

2. Breathability

   • Science: Membranes (e.g., GORE-TEX) use tiny pores to block water droplets while allowing vapor (sweat) to escape.
   • Metric: Moisture Vapor Transmission Rate (MVTR). Higher MVTR = faster sweat evaporation.

Why Balance Matters:
A jacket that’s fully waterproof but lacks breathability will leave you drenched in sweat during hikes. Conversely, overly breathable jackets may fail in heavy rain.

Part 2: Key Features to Look For

1. Waterproof Rating

   • Daily Use: 5,000–10,000mm HH (light rain to moderate downpours).
   • Extreme Conditions: 20,000mm+ HH (mountaineering, alpine expeditions).

2. Breathable Membranes

   • GORE-TEX Pro: Best for high-intensity activities; 3x more breathable than standard GORE-TEX.
   • Event™ Technology: Uses eVent® membrane for rapid airflow (ideal for hot climates).

3. Construction Details

   • Sealed Seams: Look for taped or welded seams to prevent water ingress.
   • Articulated Design: Roomy cut for layering without restricting movement.
   • Adjustable Features: Inner cuffs, storm flaps, and adjustable hoods to block wind/driving rain.

4. Weight & Packability

   • Ultralight Options: Membrane-lined softshells (e.g., TOREAD WindStopper Nano) for layering under hard shells.

Part 3: Common Pitfalls to Avoid

• Myth: "Higher waterproof rating = better performance."
  Reality: Excessive waterproofing often sacrifices breathability. Prioritize MVTR in active use.
• Neglecting Layering: A waterproof jacket alone won’t suffice. Pair with moisture-wicking base layers and insulating mid-layers.
• Ignoring Maintenance: Dirt and oils clog membrane pores. Clean jackets regularly with specialized detergents (e.g., Nikwax).

I need a new shell. I don't have the cash to own many different jackets for different types of trips. Therefore, I'm looking for the best combination of waterproof/breathable fabric, weight, durability and most of all versatility. I won't something I can wear in the winter as an outer layer and something that's not too bulky to take out in the summer for rain protection.

Also, if you can explain the pros and cons of the fabrics that would be great. Like Gore-Tex Paclite, other Gore-Tex versions, HyVent (TNF), etc. and any others you have experience with.

Thank you for your time.

All waterproof/breathable membranes are made from polyurethane with two exceptions (GoreTex and eVent), so Patagonia's H2No, North Face Hyvent etc are ALL polyurethane (PU) membranes. All polyurethane (PU) membranes perform basically the same, but some are better than others depending on the thickness of the polyurethane and what other fabrics are used in conjunction with it.

PTFE is a better material for a membrane than PU because it breathes a lot better, but the downside has long been that body oils contaminate it and cause it to lose it's waterproofness. Original Gore-Tex was PTFE but they soon discovered this contamination shortcoming and switched to a PTFE membrane with a PU layer on it to protect it. Unfortunately the PU layer is the breathability bottleneck, so Gore-Tex's PTFE/PU membranes aren't significantly better than anyone else's PU membranes. Lower end Gore-Tex might be entirely PU.

The only exception to using PU is eVent which is PTFE. eVent has found a solution to prevent body oils from wrecking the membrane. So eVent really is in a class of it's own right now.

Be careful with putting too much weight into the breathability numbers that manufacturers report. Two coats that both claim 20,000 G/M2/24 hour may not be the same or even close. There are a ton of factors that affect the breathability (ie. humidity inside the jkt, ambient humidity, temperature, wind etc). All manufacturers generally report the highest breathablity number they can achieve, but that's using ideal conditions that are no where near normal real life. My understanding is that in more real life conditions (ie. not 0% humidity outside) PTFE works much better than PU. I don't think PU breathes very well at all compared to PTFE when it's humid outside etc (which is when you really need it to breathe).

The insulation value of an eVent shell isn't going to vary significantly from a PU shell. In either case, the membrane provides very little insulation and the breathability is still low enough that significant amounts of air aren't going to be flowing through your jacket. I wouldn't rely on any shell to provide a lot of warmth out there….they just block the wind and your under layers provide the insulation.

Your criteria for a shell is tough because winter shells generally use heavier and more durable fabrics then you'd need for a summer rain jacket. If you buy something really light (ie. Marmot Mica @ ~6oz) there's a good chance you'll end up shredding it if you go skiing with it and start crashing with skis and poles flying everywhere. If you can afford it, I would buy a lightweight 2.5 layer shell for the summer and a more durable and heavier 3 layer shell for the winter. For the summer I would buy a North Face Triumph Anorak if minimizing weight is the goal, or I would buy a light eVent jkt if breathablity is very important to you. You could probably get double duty out of the heavier eVent shell, but I wouldn't try this with the Triumph Anorak or Marmot Mica.
