Cold Weather Layering Part 3: How to Choose an Insulation Layer

Published on March 30, 2023
Duration: 21:14

This video details the crucial insulation layer for cold weather, emphasizing modern layering systems over outdated 'mid-layer' concepts. It compares down and synthetic insulations, explaining fill power vs. fill weight and recommending synthetics like Primaloft for wet conditions and extended field use. The importance of sizing insulation for tactical gear compatibility and specific product recommendations for jackets and pants are also covered.

Quick Summary

Choose insulation based on conditions: synthetics like Primaloft excel when wet and are durable for field use, retaining over 90% warmth. Down offers superior warmth-to-weight and compressibility but fails when wet unless treated. Understand Fill Power (loft) vs. Fill Weight (amount) for accurate warmth assessment.

Frequently Asked Questions

What is the difference between fill power and fill weight in insulation?

Fill Power (e.g., 450-900) measures the loft and efficiency of down insulation, indicating how much space a given weight of down occupies. Fill Weight (in grams or ounces) is the actual amount of insulation used in the garment, directly determining its overall warmth.

Why is synthetic insulation often preferred over down for tactical cold weather gear?

Synthetic insulation, like Primaloft, retains over 90% of its warmth even when wet, making it more reliable in damp conditions. It's also generally more durable and less prone to catastrophic failure if the outer fabric is compromised.

How should I size insulation layers for tactical use?

Insulation layers intended for use over tactical gear, such as 'belay jackets,' should be sized up. This allows them to fit comfortably over plate carriers or chest rigs, enabling you to add warmth quickly without removing essential equipment.

What are the key advantages of a puffy vest for cold weather layering?

Puffy vests serve as excellent active insulation. They provide crucial core warmth while allowing heat to escape efficiently through the armpits, preventing overheating during activity. They are also highly packable and offer low bulk.
