Layering Basics – Open Country

Weather changes fast on the mountain. In a single day, a backcountry hunter may experience a half-dozen different conditions. Energy levels vary too, as you climb, stalk and spot. Wearing the right layers will help keep you warm, dry – and focused – in the most challenging terrain.

Typical open country layering scenario

This chart represents an everyday scenario you may experience on the mountainside. The bottom line: Instantaneous changes in weather and expended energy dictate the need for layering.

Layers

Cold before activity

Shed waterproof outer layer (allows better heat transfer)

  • Shed waterproof outer layer
  • Shed insulation layer (keeps you from sweating)

All layers keep you warm with decreased activity and dry from the elements
