Quick Answer
For overnight campsites, choose a moisture barrier that is waterproof, breathable, and suitable for the season and climate. Look for materials like nylon, polyester, or silnylon, which provide a balance of durability and weight. Consider the terrain and potential weather conditions when selecting a barrier.
Evaluating Moisture Barriers
When selecting a moisture barrier, consider the expected weather conditions. For warm and humid climates, look for a barrier with a high water vapor permeability (WVP) rating to prevent condensation buildup. A WVP rating of 1,000-2,000 g/m²/day is suitable for most applications.
Choosing the Right Material
Different materials offer varying levels of waterproofness, breathability, and durability. Nylon and polyester are popular choices for moisture barriers, offering a balance of weight, strength, and water resistance. Silnylon, a silicone-coated nylon fabric, provides an excellent balance of waterproofness and breathability. When choosing a material, consider the intended use, terrain, and potential weather conditions.
Additional Factors to Consider
When selecting a moisture barrier, also consider the following factors:
- Weight: Lightweight barriers are ideal for backpacking and long-distance trips, while heavier barriers may be more suitable for car camping or sheltered areas.
- Durability: Choose a barrier with a high tear resistance and abrasion resistance to withstand harsh weather conditions and rough terrain.
- Seam construction: Look for barriers with sealed seams to prevent water ingress and extend the lifespan of the barrier.
