This 11 Person Extended Dome Tent features CORE H20 Block Technology- water repellent fabrics with active bead technology for faster water runoff paired with sealed seams on rainfly, doors, and windows. Setup is simple with color-coded fiberglass poles and sleeves. Attach the rainfly fully, or roll the sides to partially expose the mesh roof ceiling for optimal air flow and star gazing. 

The advanced venting system uses the adjustable air intake vent designed to draw in cool air from the ground while the mesh ceiling allows hot air to escape keeping you comfortable all season.
