Quick Answer
Vapor barrier clothing features an impermeable membrane that prevents moisture from escaping, typically made of materials like polyethylene or polyester. This helps maintain body heat and prevents cold-related injuries. Look for waterproof, breathable, and wind-resistant properties.
Choosing the Right Material
When selecting vapor barrier clothing, look for materials with a high water resistance rating, such as Gore-Tex or similar membrane technology. These materials can withstand water pressure and prevent moisture from entering the garment. Consider a material with a 20,000 mm water column rating or higher for optimal water resistance.
Insulation and Breathability
Ensure the vapor barrier clothing has a breathable layer to prevent moisture buildup. This can be achieved through mesh panels or ventilation zones. Opt for insulation with good loft retention, such as Polarguard or Hollofil, to maintain warmth even when wet. Avoid down insulation in extreme wet conditions as it loses loft.
Additional Features and Considerations
Consider vapor barrier clothing with adjustable cuffs, hem, and hood to prevent cold air and moisture entry. A waterproof zipper or zipper garage protects against wind-driven rain. Additionally, a built-in face mask or neck gaiter can prevent cold air from entering the face. Ensure the garment has a secure fit to prevent heat loss and maintain body warmth. Avoid over- or under-dressing, as this can lead to heat loss or moisture buildup.
