Brunel University industrial design and technology student Luke Pannell created this "Star Wars" helmet to help bicyclist breathe better:
The helmet was created to filter out particles which irritate hay fever and asthma sufferers.
It covers the cyclist's nose and mouth with a shield behind which the filtered air circulates.
Used air is expelled via a plastic tube when the cyclist exhales.
