Layering System

Layering System reference article on thruhikingwiki.com.

Overview

A layering system is a structured approach to clothing selection that uses multiple layers to regulate body temperature and moisture across a wide range of conditions.

Key points

  • Typically consists of base layers, midlayers, insulation layers, and shell layers.
  • Allows hikers to adapt quickly to changing weather and exertion levels.
  • Focuses on breathability, moisture management, and thermal efficiency.
  • Can be customized for climate, terrain, and personal comfort.

Details

The layering system is foundational to safe backcountry travel, enabling hikers to stay warm, dry, and comfortable. A well-designed system balances warmth with ventilation and reduces the risk of hypothermia or overheating. Materials such as merino wool, synthetic fleece, and lightweight insulated jackets each serve distinct roles within the system. Adjustments—adding or removing layers—are made as weather, speed, and elevation change.
