Quick Answer
For long-term survival situations, consider tarps made from waterproof and UV-resistant materials, such as polyester or nylon, with a thickness of 0.5 mm to 1 mm. Look for tarps with reinforced stitching, durable tie-down points, and a simple, compact design.
Choosing the Right Tarp
When selecting a tarp for long-term survival, prioritize durability and water resistance. A 9x13 foot (2.7x4 meter) tarp with a 0.75 mm thickness is a good starting point. Consider tarps made from Silnylon or similar materials, which offer a high balance of weight, durability, and water resistance. Silnylon tarps typically weigh between 14 and 18 ounces (400-500 grams).
Setting Up the Tarp
A well-designed tarp should be easy to set up and provide adequate shelter from the elements. Look for tarps with reinforced tie-down points and consider using a tarp with a built-in ridge line or center attachment point. Use a 6-foot (1.8-meter) length of cordage to create a sturdy ridge line between two trees or poles. Space the tie-down points 2-3 feet (0.6-0.9 meters) apart to ensure a secure and even tarp shape.
Additional Considerations
When selecting a tarp for long-term survival, also consider the color and reflectivity of the material. A darker, more muted color can help reduce visibility and minimize the risk of wildlife detection. Avoid tarps with shiny or reflective surfaces, as these can attract attention and make it more difficult to blend in with the environment.
