An umbrella with a chamber for storage of material such as an enclosure canopeum of netting. Included are mechanisms for transport and interchange of various canopeums. By turning a crank handle, netting is transported from its storage chamber to the edge of the umbrella canopy, where it can be lowered to the ground. The canopeum will then shield those under the umbrella from incursions by agents such as insect pests. Turning the crank in the opposite direction transports the canopeum to its stowed and protected position within the chamber. Canopeum accouterments facilitate attachment, removal, and interchange of canopeums having varied compositions, textures, and surface details.
