Air curtain hat and collar

This normal-looking garment incorporates a hat with a brim, and a stand collar which is set a little wider from the neck/face than normal.

Both the brim of the hat and the rim of the collar have many small nozzles or orifices in them.

A backpack mounted gas turbine powers a very high powered air pump which constantly recirculates and filters a stream of air, blasting the air upwards at supersonic velocities from the nozzles in the collar, and sucking the air in at the same rate through the orifices in the hat.

The design of the nozzles and orifices enables a smooth laminar air flow to reduce noise and turbulence.

Now you can walk through crowded shops, visit your granny in her retirement home and attend important business meetings without fear of catching contagious and dreaded lurgies.
