The Bibler Eldorado optional vestibule -- this buckle-on vestibule adds 1 1/4 pounds, requires only one stake, and provides nine square feet of additional storage area as well as a sheltered entrance during stormy weather. Covered by an awning to provide ventilation in the rain, the door unzips and toggles to the side. Made from 1.9 ounce coated ripstop nylon, and an Easton pole, the Vestibule is easily left behind on difficult climbs or in fine weather. Works for single or two door Eldorado Tents.
