Buzz Off

Mosquito nets will keep insects off you during sleeping hours, but you’re left to fend for yourself during the day. Boston inventor Thomas Prentiss offered this improvement in 1873, so you can get some exercise in fly-plagued regions and ward off sunstroke as well:

This, my invention, consists in an umbrella, sun-shade, or similar article covered with suitable gauze or netting. To the lower edge of the sun-shade, umbrella, &c., is secured a similar netting of ample dimensions, so that one or more persons can be protected under it. The height of the netting may be made so that the lower edge thereof shall reach the ground when the person who carries it is standing.

The handle can be placed in a socket in a chair or settee, or you can stroll around with it. And the whole thing folds up like an umbrella when you’re not using it. The hat, I suppose, is optional.
