I use mine to clean the visor too when nothing else is available :thumbup:
I never used to use the bag for my ski goggles, but they never lasted more than 1 season. I started using the bag and I have the same pair I bought 8 years ago! Maybe that's why I got into using the helmet bag. Then again...I've been through 3 visors this year alone from road use, and the bag wouldn't help with that.
I use my helmet bag for long term storage only - which is to say, only when the weather takes a bad dump here. Since I get ~ 9 months a year riding (including in some torrential downpours), the bag only really gets used when there is snow on the ground...
The rest of the time I'm wearing the 'ole brain bucket. :thumbup:
