Three mesh windows sit high on the walls where the breeze actually moves, and paired with the extendable floor panel they keep the interior from turning into a hot box on still afternoons. The shell is 190T polyester with a silver coating rated UPF 50+, screening up to 98 percent of ultraviolet light, and a PU layer handles light rain. Open dimensions are 100 in wide by 52 in tall, with a 50 in front porch that stretches the shaded area well past the sleeping zone for 3 to 4 adults or 2 adults with 2 kids. Gear stays organized in a large internal storage bag and 4 interior pockets. Fiberglass ribs pop the frame open with no poles to thread, and the packed shelter weighs 6 lbs, so it rides on a shoulder with the chairs.
