I’ve been mapping out ways to build a shelter that can stand up to extreme weather while using the fewest resources possible. What’s the most efficient material you’d choose for a quick, durable, low‑energy setup in the wild?

Sounds solid—just make sure the poles are pre‑tuned to the load of wind and rain, otherwise the tarp can flex too much and let water seep in. A little diagonal bracing on the corners would lock the shape better without adding much weight. You could even add a small, removable awning on the front to protect the entrance from splash. That way you keep the system lightweight yet weather‑tight.
