Snowboard Fog Wiper by Wide-i
On a different note, I use Snowboard fog wiper (by Wide-i) for my mask fogging problem. I have been using scuba mask fog wipers for my mask fogging under the water, and have been very happy with it. I don't have to take my mask off in the middle of diving to rinse the fog off from the mask. Recently when I found out that the Company also makes snowboard and ski mask version, I gave it a try, and I am very happy with these little fog wipers. You wipe using your index finger outside the mask/goggle, and inside fog gets wiped off from the mask! Easy!
