I recently bought a Shark RSI Helmet. They are advertised as having a Dual-treated (anti-scratch/anti-fog) 'Total Vision' 2.2mm visor however every morning this week my helmet has fogged up on me. I have made sure the vents are definitely open but even when moving they still donâ€™t seem to clear the visor. The only way to clear it has been to lift the visor to the first notch but on a cold morning that certainly not what I want to be doing. I realise there are products you can buy but I am interested to see how others with have found these helmets? Am I just one of the unlucky ones or is there no such thing as an anti fog visor?
