Built-in Tpu air tubes replace poles entirely, and the supplied rechargeable pump inflates the whole frame in about three minutes, which removes the sorting and threading step where most first-time pitches go wrong. Floor space measures 90.16 by 90.16 inches with a 69.69 inch peak, giving 2 to 4 sleepers room to lie out and sit up comfortably. The canopy is 210D Oxford fabric with a waterproof coating over a polyester mesh inner, and five large openings, one door, three side windows and two roof windows, ventilate the interior and open the roof to the sky on clear nights. Packed weight is 15.43 pounds in a 24.41 by 12.60 by 12.60 inch bag, compact enough for a car boot with the rest of a weekend load. Deflating is as quick as inflating when the trip ends. Spot clean the fabric and dry it fully before packing.
