In a layering system, what is the main job of the innermost layer?

Move sweat away from your skin.

  1. Keep sweat away from your skin ✔
  2. Block wind and rain
  3. Add the most puffy insulation

Why: Dress in layers: a non-cotton inner layer wicks sweat, a middle layer traps heat, and an outer shell blocks wind and rain. Add or remove layers so you don't sweat.

Huh, didn't know that: Starting a hike just a tiny bit cold helps you avoid sweating once you warm up.

The dad joke
Why do onions make great hikers? They know all about layers.
