Hiker's Layering System Explained
The 3-layer system is the foundation of proper outdoor clothing:
- Base Layer - Wicks moisture away from your skin
- Mid Layer - Traps body heat while allowing moisture to escape
- Outer Layer - Shields you from wind, rain, snow, and other elements

Why Proper Layering Matters?
Your body temperature fluctuates significantly during a hike. On uphill sections, you generate heat and sweat; during descents, you produce less heat and need more insulation. The classic advice "be bold, start cold" reminds us to begin slightly cool because your body quickly warms up during activity.
Common Layering Mistakes
- Cotton clothing - Stays wet, loses insulating properties
- Too many initial layers - Causes overheating and excessive sweating
- Delayed adjustments - Wait too long to add/remove layers
- Neglecting extremities - Head, hands, and feet lose significant heat
Seasonal Considerations
- Winter Hiking: Focus on moisture management to prevent sweat from reducing insulation effectiveness.
- Summer Hiking: Prioritize sun protection and ventilation with lightweight, UPF-rated garments.
Material Selection
- Merino wool - Natural temperature regulation, odor-resistant
- Synthetic fabrics - Quick-drying, durable, often less expensive
- Down insulation - Highest warmth-to-weight ratio, poor when wet
- Synthetic insulation - Maintains warmth when damp, dries faster
