Buying Guide
- What weight best suits your climate? Choose lightweight (165 g/m²) for mild cold or high activity, midweight (250 g/m²) for typical cold days, or heavyweight (320 g/m²) for extreme cold or wind exposure.
- How should you layer? For layering, start with a lightweight base on milder days, add midweight when temps drop, and consider a heavyweight outer shell for harsh conditions.
- Is itch resistance important? All products here use superfine merino to reduce itch; if you have very sensitive skin, confirm fabric thickness and seam design.
- Fit considerations: Look for anatomical or contoured cuts that move with your body. Some styles offer 3/4 length bottoms which can affect warmth and layering options.
- Care and durability: Merino wool requires careful washing to maintain softness and prevent shrinking. Follow garment care labels to extend life.
