What should I pack for Lapland in January?

For January in Lapland, pack heavy Merino wool base layers, thick insulation (fleece or down), windproof and waterproof outer shell, wool hat covering ears, mittens, and insulated boots rated to at least -40°C. Cold tolerance adjustment and your planned activities will modify these recommendations.

How does the 3-layer system work for Arctic temperatures?

The 3-layer system consists of: Base layer (moisture-wicking like Merino wool), Mid layer (insulation such as fleece or down to trap warmth), and Shell layer (windproof and waterproof outer protection). This system manages sweat moisture while maintaining trapped heat for Arctic conditions.

Methodology

This calculator utilizes the 3-Layer Principle adapted for Arctic conditions. Our temperature baselines are derived from 30-year averages in Sodankylä, Finland. Recommendations for "Static" activities account for the lack of metabolic heat generation, requiring approximately 2x the insulation value (Clo) compared to active skiing.
