How to Layer for Iceland’s -10°C Winters

Visiting Iceland in the heart of winter is like stepping into another world—waterfalls frozen mid-cascade, black-sand beaches dusted with snow, and the Northern Lights dancing across a clear Arctic sky. But with all that beauty comes extreme cold. Temperatures in Iceland can dip to around -10°C, and sometimes feel even colder with wind chill. That’s why layering for Iceland winter isn’t just a style choice—it’s a survival strategy.

If you’re planning your trip and wondering how to dress for -10°C, this detailed Iceland winter outfit guide will help you build the right wardrobe. From base layers for extreme cold to the best insulating mid-layers and outerwear, we’ll walk you through everything you need to stay warm, comfortable, and ready for adventure.

Why Layering Matters in Iceland

Iceland’s winter weather is famously unpredictable. One moment you’re walking under clear skies, and the next, a sudden snowstorm sweeps in. Wind and dampness can make -10°C feel like -20°C. That’s why relying on a single bulky jacket isn’t enough—you need layers that you can add or remove depending on your activity and the shifting climate.

Think of your outfit as a three-part system:

1. Base Layer – keeps sweat away from your skin.
   
   
2. Mid Layer – insulates and traps body heat.
   
   
3. Outer Layer – protects against wind, snow, and rain.
   
   

This method ensures you’re prepared for sightseeing, hiking, and even standing still while watching the aurora borealis.

Step 1: Choosing the Right Base Layers

The foundation of what to wear in Iceland winter starts with your base layer. These pieces sit directly against your skin, so they need to be breathable and moisture-wicking.

• Materials to look for: Merino wool or advanced synthetic fabrics.
  
  
• Avoid: Cotton, as it absorbs sweat and stays damp, leaving you cold.
  
  
• Examples: Long-sleeved thermal tops and leggings designed for active travel.

High-quality base layers for extreme cold help regulate body temperature whether you’re trekking glaciers or walking around Reykjavik’s streets. Think of them as your second skin—the difference between staying warm or shivering all day.

Step 2: The Insulating Mid Layer

Once you’ve locked in warmth with your base, it’s time to trap it with a mid layer. This step is often overlooked, but it’s critical for insulation in freezing weather.

• Fleece jackets – Lightweight yet warm, ideal for moving around outdoors.
  
  
• Down or synthetic insulated jackets – Perfect for when the mercury drops below -10°C.
  
  
• Wool sweaters – Stylish and functional, great for city exploring.

If you’re looking for a versatile mid-layer, a Waterproof Fleece Jacket For Women or a thermal-lined sweater makes an excellent choice. These provide warmth without excessive bulk, so you can move freely while staying cozy.

Step 3: Outerwear That Shields Against Iceland’s Weather

Your outer layer is your first defense against Iceland’s infamous wind and snow. It needs to be windproof, waterproof, and durable.

• Look for: Jackets with sealed seams, high collars, and hoods.
  
  
• Best picks: Insulated parkas, shell jackets, or waterproof coats.
  
  

For men, a Men's Parka Jacket offers superior warmth and coverage, especially during long outdoor excursions. For women, pairing a parka with a fleece mid-layer ensures reliable comfort throughout the trip.

This is where Kosha’s range of outerwear shines, combining weatherproofing with stylish functionality—ensuring you don’t just survive the cold, but also look great in your photos.

Step 4: Don’t Forget the Bottom Half

While jackets and tops often steal the spotlight, your legs need attention too. Wind and snow can make sightseeing uncomfortable if you aren’t layered properly below the waist.

• Thermal leggings or long johns – Worn under trousers for insulation.
  
  
• Waterproof pants – Essential for glacier hikes or rainy days.
  
  
• Insulated trousers – For outdoor excursions where warmth is key.
  
  

This layering combination ensures your lower half stays just as protected as your upper body, making long winter walks much more enjoyable.

Step 5: Accessories That Make All the Difference

Even with perfect layers, forgetting accessories can ruin your trip. Iceland’s winds target exposed skin, so it’s vital to cover up.

• Hats and Beanies: Choose wool or fleece-lined for maximum insulation.
  
  
• Scarves or Neck Gaiters: Protect against icy winds and add comfort.
  
  
• Gloves or Mittens: Waterproof, insulated options are best for snow activities.
  
  
• Thermal Socks: Wool socks prevent frostbite and keep feet dry.
  
  
• Sturdy Waterproof Boots: Non-slip soles are essential for icy surfaces.
  
  

Layering for unpredictable weather starts with accessories.

A little preparation here goes a long way—you’ll thank yourself when your fingers and toes stay warm during Northern Lights tours.

Dressing for Different Activities

Not every Iceland adventure demands the same wardrobe. Here’s how to adapt your Iceland -10°C clothing tips based on what you’re doing:

• City Exploring (Reykjavik): A base layer, fleece mid-layer, and parka, paired with thermal leggings and boots.
  
  
• Northern Lights Tours: Layer up with extra insulation, as you’ll be standing still outdoors for long periods.
  
  
• Glacier Hiking: Waterproof pants and jackets are non-negotiable. Wear breathable base layers since you’ll be active.
  
  
• Road Trips: Pack versatile layers you can easily remove inside the car and put back on when stepping out.
  
  

By tailoring your outfit to your activity, you’ll avoid overheating during hikes or freezing during still moments.

Packing Smart: Essentials for Iceland’s -10°C

Here’s a quick checklist to make sure you’re ready for anything:

• 2–3 sets of base layers for extreme cold
  
  
• 1–2 fleece or wool mid-layers
  
  
• 1 insulated jacket or Men's Parka Jacket
  
  
• 1 waterproof shell jacket or Waterproof Fleece Jacket For Women
  
  
• 2–3 pairs of thermal leggings or long johns
  
  
• Waterproof pants
  
  
• Warm hat, scarf, gloves, and socks
  
  
• Waterproof boots with a good grip
  
  

Smart layering starts with Kosha’s fleece-lined waterproof jacket blends warmth and utility.

Packing strategically ensures you can mix and match layers for different conditions without overstuffing your suitcase.

Common Mistakes to Avoid

Even seasoned travelers make errors when preparing for Iceland’s winters. Keep these pitfalls in mind:

• Wearing cotton: It traps moisture and leaves you cold.
  
  
• Overpacking bulky sweaters: Instead, rely on layering multiple thin but effective pieces.
  
  
• Ignoring waterproofing: Snow quickly turns to slush, and without waterproof gear, you’ll be soaked.
  
  
• Forgetting sunglasses: Even in winter, sunlight reflects off ice and snow, causing glare.
  
  
• Skimping on footwear: Sneakers won’t cut it on icy paths—invest in insulated boots.
