Winter Layering Guide (20-40°F Urban Edition)
Build the perfect cold-weather outfit for city life
The Three-Layer System
The three-layer system works best for urban winter: (1) Base layer (merino or synthetic) wicks moisture, (2) Mid layer (fleece or down) provides insulation, (3) Outer layer (shell jacket) blocks wind and precipitation. For 20-40°F city commutes, a merino base + fleece mid + windproof shell handles most conditions.
Key Tips:
- Base: Merino wool or synthetic
- Mid: Fleece for active, down for static
- Outer: Windproof shell
- Avoid cotton (holds moisture)
- Adjust layers for activity level
Base Layer Selection
Choose merino wool for odor resistance and temperature regulation, or synthetic materials for quick-drying and budget-friendly options. Avoid cotton as it retains moisture and will make you colder once you start sweating.
Mid Layer Insulation
Fleece works best for active commuting as it breathes well and continues insulating even when damp. Down jackets provide more warmth for standing around but lose insulation when wet. Synthetic insulation offers a middle ground.
Outer Layer Protection
Your outer shell should block wind and precipitation. For urban use, a lightweight windbreaker often suffices for 20-40°F temperatures. Look for features like adjustable cuffs, hem drawcords, and a hood for added versatility.
