🚨 Why is NO ONE talking about the ONE big mistake that’s making you FREEZE outside?
You’re wearing layers. You should be warm. But instead, you’re shivering.
Sound familiar?
You may THINK you know how to layer for cold weather—but you’re making a HUGE mistake that’s actually making you colder.
It happened to me on one of my first winter backpacking trips. I thought I was dressed perfectly—plenty of layers, warm jacket, good gloves. But an hour in, I was drenched in sweat. And the second I stopped moving…I started shivering uncontrollably.
Today, I want to help you avoid that mistake.
We’ll break down how layering actually works, the biggest mistake most people make, and how to fix it so you stay warm AND dry this winter.
The Purpose of Layering
Layering is NOT just about throwing on more clothes. If that were the case, you could just walk around like the Michelin Man and never feel cold. But we all know that doesn’t work.
Layering is actually about two things:
✅ Regulating your heat – Balancing warmth and breathability.
✅ Managing moisture – Because moisture = rapid heat loss.
To stay warm, you must manage moisture to prevent rapid heat loss. Sweating too much can be JUST as dangerous as falling into a frozen stream.
Here’s the science:
🔥 Sweat + cold air = RAPID heat loss
🔥 Wet clothing cools you down 25x faster than dry clothing
Add in a cold wind and you have a recipe for disaster. That’s why managing moisture is the PRIMARY purpose of a layering system. And THIS is where most people go wrong.
The #1 Mistake? Overdressing.
A lot of new winter hikers layer up too much, thinking:
“More layers = more warmth.”
But instead, they sweat like crazy, soak their base layers, and then FREEZE the moment they stop.
Ever taken a break on a winter hike and felt a chill creep in almost instantly? That’s your wet clothing cooling you down—FAST.
So, should you just wear fewer layers? Well… yes and no. If you're hiking uphill, you're going to sweat—there’s no way around it. So it's NOT just about how many layers you wear—it’s about how you use them.
✅ Have the RIGHT layers
✅ Know HOW to use them properly
Understanding the Layers
1. Base Layer: The Most Important Layer
Your base layer is your first line of defense against sweat.
✔ Wicks moisture away from your skin
✔ Helps regulate temperature
Choosing the Right Base Layer:
🟢 Synthetic – Best at moisture-wicking, but can smell terrible after heavy use.
🟢 Wool – Naturally odor-resistant, but retains moisture a bit more than synthetic.
❌ Cotton – NEVER wear cotton! It holds water like a sponge and traps it against your skin.
🚨 Personal Take:
"My go-to base layer is the ULTRA Merino 145 Zip-T Hoody from Kuiu. It’s moisture-wicking, itch-free, and naturally odor-resistant. I’ve worn it from single digits to mid-90s and it performs great. I just wish it was a little more durable."
2. Mid-Layers: The Sweat Managers
Mid-layers are often confused with insulating layers, but they’re not the same.
✅ They add warmth
✅ They help regulate heat & moisture while moving
🚨 BIG RULE: If you’re sweating in your mid-layer, you need to vent or remove it.
If you’re moving uphill and already warm, your base layer + shell might be enough. If you feel cold while moving, add a mid-layer.
📌 Quick Tip: Don’t take too long adding or removing layers—if you’re hiking with others, they may get cold waiting for you!
3. Insulating Layers: For When You Stop Moving
Mid-layers breathe and help wick moisture. Insulating layers trap heat. That’s it. You should ONLY wear an insulation layer when you’re NOT moving. Otherwise, you’ll overheat & soak your base layer.
4. The Outer Shell: The Final Barrier
A good winter shell is just that—a shell. It doesn’t provide insulation but instead:
✔ Blocks wind
✔ Keeps wet snow from soaking your inner layers
🚨 The Truth About Waterproof Shells: Even the best waterproof-breathable shells struggle to vent sweat fast enough when you’re working hard. That’s why ventilation (pit zips!) is just as important as waterproofing.
🚨 Personal Take:
"I used to think all waterproof jackets were the same—until I hiked in a cheap rain shell with NO vents. I was soaked from the inside out within an hour. Now, I won’t wear a shell in winter unless it has pit zips!"
How to Use Your Layers Effectively
1️⃣ Be Bold, Start Cold
🚨 DON’T layer up before you start hiking.
If you’re a little chilly at the start, that’s perfect—you’ll warm up as you move.
2️⃣ Micromanage Sweat
Too hot? Remove a layer, unzip your jacket, open pit zips.
3️⃣ Know When to Wear Each Layer
✔ Start cold.
✔ Regulate sweat.
✔ Use insulation only when not moving.
Now that you know how to use layers effectively, you can avoid one of the biggest mistakes hikers make in the backcountry.
