Layers

Insulation layers

Active fleeces and static belay puffies. The jacket you hike in is rarely the jacket you sit in.

Insulation has two jobs that fight each other. Moving uphill, you want less of it, or a fleece you can vent. Stopped at camp, you want a hooded puffy that does nothing while you walk. Buying one jacket for both jobs is how people sweat through their down.

Down packs smaller and collapses when wet. Synthetic insulation is bulkier and less fussy in rain. A sun hoodie is a layer too: it is the shirt that keeps you from needing the shell on a bright, dry day.

How to choose

  • Separate the hiking layer from the camp layer.
  • A hood is worth more than ten extra grams at camp.
  • Do not stuff a wet down jacket into the bottom of the pack and hope.
