Req 5b — Outdoor Clothing

5b.
Show that you know the proper clothing to wear while in the outdoors during extremely hot and cold weather and during wet conditions.

Your clothing is your first line of defense against the environment. A Scout in the right gear can hike comfortably all day; the same Scout in wrong clothes will be miserable in minutes. Clothing systems work by trapping air layers next to your skin—the more you understand about how to layer, the more you control your survival.

The Layering System

The key to outdoor clothing is layering—wearing multiple thin layers you can add and remove based on conditions. This gives you precise control over your body temperature and lets you adapt to changing weather.

Layer 1: Base Layer (Moisture Management)

The base layer sits against your skin. Its job is to pull sweat away from your body (called wicking) so you stay dry, not to insulate you.

Best materials:

When to wear it: Always. Even in hot weather, a good base layer keeps you dry.

Layer 2: Insulating Layer (Warmth)

The insulating layer traps dead air and creates warmth. This is where you feel the difference between cold and comfortable.

Best materials in different conditions:

Cold weather:

Wet/humid conditions:

Hot weather:

How to choose: In dry cold, down is unbeatable. In wet or unpredictable weather, fleece or wool are more reliable.

Layer 3: Shell Layer (Wind & Water Protection)

The shell is your armor against wind and rain. A good shell is breathable so sweat can escape while blocking external moisture.

Best materials:

Wind protection: A shell that’s water-resistant also blocks wind. Wind can increase heat loss 25x, so a shell is critical in windy conditions even if rain isn’t expected.

Three layering systems compared: cold weather, hot weather, and wet weather

Clothing for Extremely Cold Weather

When temperatures drop below 30°F, proper clothing is the difference between a fun hike and a life-threatening situation.

The Cold Weather System

  1. Base layer: Synthetic or merino wool (never cotton)
  2. Insulating layer: Thick fleece or wool. Consider wearing two layers if temperature is below 0°F.
  3. Shell layer: Wind-resistant jacket and pants. Any breeze will kill you faster than still-air cold.

Cold Weather Mistakes to Avoid

Don’t overdress. Overdressing makes you sweat. Wet layers are death. Wear just enough that you’re cool at the start—you’ll warm up as you move.

Don’t ignore shivering. Shivering means your body is trying to generate heat. Stop and add a layer before shivering becomes uncontrollable.

Don’t wear jeans. Denim absorbs water, dries slowly, and loses insulation when wet. Wear synthetic or wool pants.

Clothing for Hot and Dry Weather

In extreme heat, your enemy is sun exposure and dehydration. Clothing serves to protect you from the sun, not to warm you.

The Hot Weather System

  1. Base layer: Synthetic or merino wool. Light colors reflect heat; dark colors absorb it. Wear light-colored, moisture-wicking shirts.
  2. Insulating layer: Skip it. You want air exposure, not insulation.
  3. Shell layer: A light, breathable shell or lightweight long sleeves. Seems counterintuitive, but long sleeves protect your arms from sun damage and reflect some heat.

Additional Hot Weather Gear

Hot Weather Mistakes to Avoid

Don’t go shirtless. You’ll get severe sunburn and lose fluids through burned skin.

Don’t wear dark colors. They absorb heat. Light colors (white, tan, pale yellow) reflect it.

Don’t restrict airflow. Tight clothing traps heat. Wear loose, breathable garments.

Don’t rely on shade alone. Reflective surfaces (sand, rock, water) bounce heat and UV rays. Wear sun-protective clothing even in shade.

Clothing for Wet Conditions

Wet weather requires waterproof protection without trapping moisture that leads to hypothermia.

The Wet Weather System

  1. Base layer: Synthetic (merino wool works too). Cotton is forbidden—it absorbs water.
  2. Insulating layer: Fleece or wool if it’s cool. Thin or skip if it’s warm and rainy.
  3. Shell layer: Waterproof jacket and pants. “Water-resistant” isn’t enough—true waterproofing keeps rain out.

Additional Wet Weather Gear

Wet Weather Mistakes to Avoid

Don’t use a cotton rain jacket. It might block surface water but still absorbs moisture and doesn’t dry quickly. Use synthetic waterproof shell.

Don’t overheat in heavy rain gear. Modern shells are breathable. If you’re overheating and sweating inside the jacket, you’re moving too fast. Slow down and let sweat escape.

Don’t ignore damp conditions. Rain plus cool temperatures equals hypothermia risk. Dress for wet weather even if it’s just “maybe” raining.

Don’t go barefoot or in sandals. Wet feet in cold weather is dangerous. Proper footwear is non-negotiable.

Footwear for Outdoor Conditions

Your feet are your foundation. Bad footwear ruins hikes and creates survival situations.
