Icebreaker
Everyday 260 Crewe
The Icebreaker Everyday 260 Crewe takes the top spot in our Wool Base Layers list for 2026. Heavyweight everyday merino. The default winter base layer for a reason. Merino handles a wider comfort range than synthetics, resists odor for days, and stays warm when damp. Weight (typically 150 g/m² summer, 200–260 g/m² winter) and fit matter more than brand. Blended merino (with a small amount of nylon) is more durable and worth it for hiking-weight tops. Across the field we compared, nothing else combined the same balance of build quality, real-world usability, and value. That's why the Icebreaker Everyday 260 Crewe earns the #1 slot for 2026, and why it's the piece we most often recommend when someone asks where to start.
