Proper layering can protect you from the cold, ensure mobility, and help you stay dry when working in snowy or icy conditions. Each layer serves a purpose. This guide breaks down how to layer for safety and comfort during fieldwork in extreme winter conditions.

1. Base Layer: Moisture Control: The base layer touches your skin and manages moisture. Choose a material that wicks sweat and dries quickly. Avoid cotton, as it absorbs moisture and keeps you cold.

Look for materials like:

  • Merino wool: Soft, warm, and naturally odor-resistant.
  • FR base layer fabrics: Lightweight and practical at wicking moisture.  Make sure they comply with ASTM F1506. Do not use synthetic materials under FR layers as they can melt and increase the severity of injury.

The base layer should fit snugly but not restrict movement.

2. Middle Layer: Insulation: The middle layer traps heat and keeps your body warm. This layer should be thicker than the base layer but still breathable.

Good options include:

  • FR Fleece: Lightweight and warm.  Can be stand alone garments or liners to outerwear shells.
  • FR Insulation:  FR quilted liners are available and can be quilted to a variety of FR fabrics.

3. Outer Layer: Protection from Elements: The outer layer shields you from wind, snow, and water.

Look for jackets and pants with the following features:

  • Waterproofing: Prevents snow and rain from soaking through.
  • Windproofing: Blocks cold gusts to maintain body heat.
  • Breathability: Allows moisture from sweat to escape, keeping you dry.

Consider flame-resistant (FR) rainwear if working in industries exposed to fire hazards. For example, NASCO FR Raingear combines winter protection with safety features.

4. Accessories: Covering Extremities: Cold weather can affect uncovered areas quickly. 

Protect these parts of your body:

  • Head and Neck: Wear insulated hats or balaclavas. Use a scarf or neck gaiter to protect your neck.
  • Hands: Wear insulated, waterproof gloves or mittens.
  • Feet: Use wool socks and waterproof boots with proper insulation.

5. Layering Tips for Maximum Efficiency

  • Adjust layers as needed: Remove layers during high activity to prevent sweating. Add layers during rest to retain warmth.
  • Use zippers and vents: Jackets with zippers or pit vents allow you to release heat without removing layers.
  • Inspect gear regularly: Check for tears or worn-out insulation, especially in FR rainwear.

6. Maintaining Your Winter Gear: Proper care extends the lifespan of your winter gear.

Follow these tips:

  • Wash after use: Clean off dirt and sweat to prevent material degradation.
  • Air dry: Avoid direct heat to maintain waterproof coatings.
  • Store properly: Keep gear in a dry, cool place when not in use.

Layering effectively for snow and ice ensures safety, comfort, and productivity during fieldwork. You can stay warm, dry, and protected by choosing the right materials and understanding each layer’s purpose. Proper care for your winter gear further enhances its durability, allowing you to focus on the task without compromising safety.
