Are there fabric covers that zip to cover the mesh on the doors and windows?
I camp in the desert and the beach - wind driven dust easily sifts through the mesh.
No, that's just one of the downsides to mesh tents. I just take a tent that has a rainfly that goes really close to the ground or throw down my pack or something on the wind side of the tent.
Actually, the doors do have zip covers (2 layers- mesh outside, nylon inside). Definitely a nice feature for the option of some extra privacy.
