How many sets of clothing do you need on a backpacking trip?

Answer: Two sets—one for hiking and one for sleeping.

Wear the same hiking clothes every day, no matter how many days you hike. Any more than two sets will be too heavy and bulky. Your clothes will stink after a few days—join the club!

Exception: It might be wise to bring one or two extra pairs of dry socks. Wet socks can cause blisters. However, dry socks aren’t much help if your shoes are wet. In wet shoes, you can keep socks dry for a while by wearing plastic bags over them, but they’ll eventually become wet from sweat since plastic bags aren’t breathable. 

Your insulated jacket and sleeping clothes must always stay dry. Never wear them while hiking, because they may get wet from perspiration. Always keep them in a waterproof bag so they’ll stay dry if you fall into a creek or get hit with a downpour. This is a safety issue to prevent hypothermia. Along with your sleeping bag, guard your insulated jacket and sleeping clothes with your life!

Clothing Layers

Clothing is typically divided into 3 layers:

1. Inner layer (base layer)

Wicks moisture from your skin to prevent evaporative cooling at cold temperatures.

Examples:

    • Base-layer top made of merino wool or breathable, moisture-wicking synthetic fabric
    • Base-layer bottoms (long underwear) made of merino wool or breathable, moisture-wicking synthetic fabric

2. Mid layer (insulating layer)

Traps body heat.

Examples:

    • Polyester fleece jacket
    • Wool or synthetic sweater

The terms “mid-layer” and “insulating layer” are usually used for clothes worn on the upper body.

You can wear more than one mid layer.

When you’re at rest in the cold, you can wear an insulated jacket over a fleece jacket. An insulated jacket can be considered both a mid and outer layer.

3. Outer layer (shell)

Protects your mid layer from rain, snow, and wind.

Examples:

    • Wind jacket
    • Wind shirt
    • Rain gear
    • Soft shell

Multiple thin layers are warmer and allow better thermal regulation and moisture management than a single thick layer. You can remove layers to prevent sweat buildup when you overheat, and you can add layers when you’re cold.

Typical Example of Layering for Cold Weather

  • Merino-wool or breathable, moisture-wicking synthetic base-layer top
  • Merino-wool or breathable, moisture-wicking synthetic base-layer bottoms
  • Breathable synthetic pants
  • Mid-weight (200-300 gsm) polyester fleece jacket
  • Puffy jacket containing down or synthetic insulation
