The unique POP UP design has no loose parts and can be set up in less than 1 minute and taken down in less than 1 minute. Just push out on walls and up on the roof and the whole shelter just pops into place. Could not be easier. Unlike other beach tents that have curved sides the cube design of our shelter gives maximum space inside. Can fit a family of 4 comfortably. The shelter has vented mesh areas on each side wall to allow ocean breeze to blow through the shelter. When folded our beach tent is smaller than a beach umbrella. The shelter folds easily and then just roll up and insert into the included carry bag. We are so confident that you will love our beach cube tent that you can buy it and try it. If not totally satisfied then just return within 30 days for a full refund.
