What do you use for a outside portable shelter?

we have a nice 12X12 screened in "room" with no floor, but hanging pieces to fill in at the bottom. Got it at Dick's sporting goods for about $85 on sale. It has outside poles with stretch string inside and they all fold up into a bag about 28" long. You can also tie back opposite sides from zippers for better ventilation. Can't remember the company name.
