The Three-Layer System
Base layer moves sweat off skin. Mid layer traps warmth. Shell blocks wind and rain. Adjust in small steps before you overheat or chill.
Gear
- Base: merino wool or synthetic — avoid cotton.
- Mid: fleece or light down/synthetic puffy.
- Shell: waterproof-breathable jacket with pit zips if possible.
- Add a wind shirt for fast-moving summer days above treeline.
- Pack a warm hat and gloves even in June — Nordic summits are cold.
Trail Tips
- Start slightly cool at the trailhead — you will warm up in ten minutes.
- Stop and add a layer before you start shivering.
- Ventilate early when climbing; sweat is what chills you at the top.
