UNICEF wanted straight walls on the tent to add more interior space, even though angled sides are stronger; it also wanted the new design to be sturdy in winds as fast as 74 miles an hour, something that some manufacturers said wasn’t possible.
The final design used several tweaks to become stronger, including improvements in how the tent is anchored in the ground, the quality of the tent’s frame, and the position of guy ropes. (When the tents were eventually tested in a wind tunnel, they withstood hurricane-level winds.) On hot days, the tent stays cooler because of large mosquito-net-covered windows on opposing sides that improve airflow. Outside, a second layer above the roof, called a shade net, helps deflect the sun and creates a wind tunnel that blows air down into the tent. In a heavy storm, the shade net is designed to also prevent rain or snow from building up and collapsing the tent. For colder climates, it has a winter liner that can be added to keep it insulated.
