The fabric is double ripstop 420d nylon with ballistics reinforcements and clip-in points labeled “Wall Side” and “Air Side.” The frame and HotShot connectors are built from 6061 T-6 45 mm (1 1/8”) machined and anodized aluminum. HotShots make assembly easy with a sixth connector that lets the last pole slide, with a heart-calming click, past a rubber bumper and into place. The wall-side connectors are covered with bumpers for durability. It levels out using a six-point buckle suspension system, and the spreader bars maintain maximum width, even with two large big-wall masters on board. A large, reinforced mesh drain hole is built in the center of each bed.
