Carbon fiber tent poles are among the best materials for tent poles because of their durability and ultralight construction. Many professional guides and outdoor athletes use them, but they have a high price point.  Aluminum alloy tent poles are far more affordable while still being durable, lightweight, and flexible. They hold up well in most conditions, but they will corrode quickly if you camp or travel near saltwater. If you look strictly for durability, steel tent poles will be the strongest. They are very heavy and don’t work well if you carry your gear.
