The Core Three-Person Instant Dome Tent features stress-free setup in 30 seconds! The poles are pre-attached to the tent; just unpack, unfold, and extend. Core H20 Block Technology combines water repellent fabrics with active bead technology for faster water runoff paired with sealed seams and rain-resistant door/window seals. Additionally, the fully-taped rain fly is removable in warmer weather to expose panoramic mesh windows and ceiling. 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. The CORE Three-Person Instant Dome Tent also features zippered privacy panels on doors and windows and keeps your gear organized with the included gear loft with lantern hook and organizer pockets.
