A tent-like apparatus which has a substantial portion of its roof cut out to form a roof opening. Fastener means are provided around the roof opening, and various types of inserts each having its own fastener about its peripheral edge and each being sized to be fitted within the roof opening and the two fastener portions releasably secured together. The roof opening may be uncovered to provide a direct view and air supply but relatively no protection from inclement weather, insects and the like. A first panel insert may include conventional tent material. A sheet of flexible transparent plastic material may be provided as an insert to provide a clear unobstructed view, protection from the effects of inclement weather, insects and the like, solar heating within the interior of the tent even in relatively cold weather so long as the sun is shining, and sufficient ultraviolet radiation to the tent interior to permit the occupant therein to obtain a suntan in any type of sunny weather. Lastly, a mesh-like screen panel insert may be employed to provide a somewhat reduced view, to keep out insects, and to allow the air in.
