But the Rainpal might just actually work.
This new addition to the ever increasing canon of ‘getting rain away from visor’ devices was designed in the Czech Republic and is currently being manufactured in China.
Coming in a neat, carry-case and being battery operated, the Rainpal fits over the top of your existing visor and according to the designers can withstand speeds in excess of 150 km/h – thanks to tiny suction cups and clamps.
Just like your car windscreen wiper, this motorcycle helmet version comes with adjustable speeds (wirelessly controlled) and wash jets.
Starting from £59, this is – of course – a crowdsourced project. So if you like what you see and want to add your name to the long list of people who have put money behind contraptions that aim to deter rain from a bikers’ face then you can do so here.
