Q

Layer of the Layering System?

A

The Base Layer: Moisture Management
The Middle Layer: Insulation Layer
The Outer Layer: Shell Protection

17
Q

The Base Layer

A

Moisture Management
-The first layer in direct contact with your skin.
-It does not retain moisture.
-Made of polypropylene, merino wool
-lightweight.
It is important your clothing works in a way that cn cool down quickly but not too fast.

18
Q

The Middle Layer

A

Insulation Layer

  • Retains body heat which creates still or dead air around body.
  • Still air decreases heat exchange between your body and the outside world.
  • Examples; Down jackets, polar fleece.
19
Q

The Outer Layer

A

Shell Protection

  • Protection from wind.
  • Protection from moisture;rain and snow.
  • Cutting body moisture.
  • Examples; Gortex, Extent Shell.
