Cheap tents might not survive your next trip to Yellowstone. The Big Agnes Royal Flush 3 mountaineering tent uses Cordura fabric that's coated with a silicone treatment and a 1200-mm polyurethane coating. The poles are made from TH72M aluminum to make them more durable. Even the seams are recoated with waterproof polyurethane. This 8-pounder is designed for serious backpackers—or people who never want to buy another tent.
