WILLIAM S The shade has loops to fasten a wall on ANY opening, so I imagine one could put the fasteners from an adjoining wall thru these loops. The wall fasteners are just oblong buttons that go thru the loops and then turned 90 degrees.

PEGGY D Yes, the Kelty sunshade can accommodate 3 side panels for privacy, very handy when camping or sheltering in a public area. The corners of the panels are easily attached to/detached from the basic shelter for access.

WADE B walls can be added to all sides of the shelter. If you are using it like a tent that might be an option. We have a wall for one side and use the sun shade at the beach. if it is really bright/hot, we can add the wall to the affected side; however, this does restrict some of the sea breeze, and it can get stagnant/hot inside. If you can would recommend keeping the sides open for air flow.

ERIC M Yes. Each side can have a wall attached to make it more private. I did this on a camping trip when I needed to change clothing and it worked very well. Keep in mind that the walls do NOT go all the way to the floor. So if you need privacy at feet level you are out of luck. Hope this helps.
