Beach tents are often a simplified embodiment of dome visit site tent and provide a useful (relatively sand-free) place to temporarily store beach equipment, but are at most showerproof. Some beach tents use specially treated fabric which is opaque to ultra-violet light, and so provide some protection against sunburn. Maximum height is practically about 120 cm (4 ft), and they are ordinarily not large enough for an adult to lie down in.
The elemental dome has a rectangular landing and two poles which cross at the peak; each pole runs in a smooth bend from individually bottom corner, up to the peak, and then down to the diagonally opposite ground corner. There are habitually distinctive fittings at each corner which fit into sockets at the ends of each pole - pole tension keeps everything in shape.
