ABSTRACT:
A small, lightweight tent having enhanced comfort and stability includes a flexible covering having two generally similar side walls. Two resiliently flexible pole members are held flexed by the side walls so as to hold the side walls tense and thereby shape and support the tent. In this way, the tent is made freestanding. The tent further includes a flared top portion closed only by a net material to not only enhance ventilation of the tent, but also permit viewing of the sky.
