Abstract
Abstract A tent comprising a flexible porous sheet having an inner face and an outer face and a resilient frame attached to the sheet. The resilient frame is stressed so that the frame can shape the sheet into an enclosure having a peripheral wall, a closed top, an opening at the front, and a shroud for closing the opening. The shroud is of substantially greater length than the height of the opening. A peripheral region of the sheet extends from the perimeter of the enclosure to form a seal with the surface which supports the tent.
