Just an fyi - I have this. It is awesome, lightweight, and much more compact than other options. It comes with extra guy lines for stability in wind, and even includes the stakes for the extra guy lines. It comes with a single panel, but you can buy additional panels here: https://mountainsmith.com/mountain-shade-dome-accessory-panel.html Seems they are out of stock at the moment, but trust me, if a bunch of people ask for it, they will get more. Also, if you need to, it is really easy to reposition after assembling, just by removing the stakes. I didn't use the stakes until the wind picked up, and just moved the panel as needed. The panel takes a minute to move. If you were really creative and good with a sewing machine, the panel is simple enough that you could use it as a pattern for bug screening.
