8.5ft Dyneema Tarp Review: 11ft Hammock Coverage Test

This review details a field test of an 8.5ft x 8.5ft Dyneema tarp used to cover an 11ft hammock. Initial concerns arose regarding the tarp's adequacy given the size difference, prompting a diagonal setup to maximize coverage. The test was conducted under challenging conditions—a dark, windy night accompanied by thunderstorms—providing a rigorous assessment of the tarp's performance in realistic weather. The review meticulously documents the setup process and the tarp's effectiveness during both a prolonged period of rainfall and an overnight stay in inclement weather.The primary focus is on evaluating the tarp's ability to keep the hammock dry, despite its smaller dimensions. The findings offer valuable insights into the practicality and limitations of using a smaller tarp for a longer hammock, considering both its advantages in terms of pack size and weight, and any compromises in weather protection. The ultimate aim is to determine if this specific Dyneema tarp provides sufficient protection for backpacking adventures in varied weather conditions.

Overnight Performance and Results

Leaving the setup overnight in continued rain and wind allowed for a comprehensive test. This extended evaluation ensured a more accurate assessment of the tarp's protective capabilities.

Even after an entire night, the hammock remained entirely dry. This exceeded initial expectations, demonstrating the tarp's robust weather protection.

The lack of water running down the straps and onto the hammock further confirmed the effectiveness of the diagonal setup and the tarp's design.
