Packing for Iceland is all about mastering the art of layers. In the land of fire and ice, you can realistically experience all four seasons in a single hour—from bright sunshine to horizontal rain. For campervan travelers, the challenge is simple but crucial: you must minimize bulk to save space in your van while maximizing functionality for the outdoors. Here is my battle-tested guide to staying warm, dry, and comfortable throughout your entire journey.

The 3-Layer System

Layer 1: The Base (Wicking)

The foundation of your warmth starts directly on your skin. Choose materials that actively manage moisture and pull sweat away from your body.

• Merino Wool Thermals: High-quality tops and bottoms are non-negotiable. Unlike synthetic fabrics, merino wool is naturally odor-resistant and keeps you warm even if the fibers get damp from a sudden mist.

• Wool Socks: Pack 4–5 pairs of varying thicknesses. Pro Tip: Combine a thin liner sock with a thick wool outer sock to reduce friction and prevent blisters during long hikes on uneven lava fields.

Layer 2: The Mid (Insulation)

This layer is responsible for trapping your body heat and creating a warm microclimate around you.

• Fleece or Half-Zips: These provide excellent breathability and are easy to peel off when the sun finally breaks through the clouds.

• Insulated Down Jacket: A lightweight “puffy” jacket is your best friend. It provides maximum warmth-to-weight ratio and is perfect for chilly evenings at the campsite or while waiting for the Northern Lights to appear.

Layer 3: The Shell (Protection)

Your shield against the Icelandic elements.

• Waterproof Jacket: Must be 100% waterproof and windproof, not just “water-resistant.”

• Waterproof Pants: Essential for waterfalls like Skógafoss, where the spray will soak you in seconds.
