A portable shelter comprises: a frame which comprises a plurality of ribs and a central connection member to which an end of each rib is movably attached, for movement between a compact closed configuration and an open, extended configuration. A flexible, weatherproof, sheet-form covering, is fitted to the frame, to complete the shelter. The frame can readily be raised and taken down, and for typical sizes, this will require no more than two people. The shelter can provide adequate head room for welding and other activities.
