Dear Sena, your new Smart Helmet with Noise-Control is a great idea.

Presently it does not specify how you plan to ensure the visor will stay free of fog and will not condense on the inside from your breathing-out especially while rinding in cool temperatures.

In my opinion the best solution will be to outfit the visor with:

See attachment for details.

Note it must be this 100% max vision type, as only that one, as the name says, ensures full vision and is special made for the visor shape.

Same is already used and proofed by many other famous helmet brands in the same higher price range.

Looking forward to see the helmet on the market with this feature included.
