Why Norse Merino won the test

The Norse Merino Double-Layer Zip Polo stands out thanks to a construction developed for prolonged use in demanding conditions.

Durable outer layer in interlock merino wool that retains warmth
Breathable merino mesh on the inside to improve ventilation and moisture transport
Stable comfort even when the garment becomes damp
Well suited for high-intensity activity in cool to cold conditions

The combination of insulation, ventilation, and comfort resulted in a top score in the test.

When to choose a double-layer wool system

A double-layer wool base layer is designed for situations where intensity and conditions vary.

During prolonged activity
When you sweat but still need insulation
When conditions shift between movement and rest
When next-to-skin comfort is essential throughout the day

The inner merino mesh enhances ventilation, while the outer layer provides insulation. Together, they help maintain a more stable microclimate close to the body.
