INSTANT SETUP: Setups in 2 minutes or less! The poles are pre-attached to the tent- just unpack, unfold, lift legs into position and extend legs until they click into place. COMFORTABLE: The water repellent rainfly is removable in warmer weather to expose the mesh ceiling for panoramic views for star gazing on clear summer nights. Also, 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. TWO ENTRYWAY AND THREE ROOM OPTIONS: Enter from the side D-Door or from the side T-Door which features two attachable room dividers which gives you freedom to create multiple separate living and sleeping spaces.
