The Extreme 3 is a freestanding three-pole tent with an extremely strong and sturdy pole configuration. Three lightweight aircraft alloy aluminum poles set up easily with pole clips that snap in place. Polyester rainfly and nylon floor are urethane coated, with factory-sealed seams for waterproofness. The two vestibules also serve as guy-out points that stabilize the tent when the weather gets a little nasty. Rainfly attaches securely to the tent with buckles and adjustable webbing mesh ceiling vents allow airflow to prevent condensation inside the tent. Special buy.
