500psi Mask Defog Review - $10.95 - Scuba Gear Customer Reviews - Bought this product at the recommendation of my racing buddy, to use on my face shield for my Go Kart Racing Helmet, because we are required to wear full face helmets and we are racing at night. In the past, the shield would fog up from time to time especially as the night got cooler and breathing with the face shield down. Applied the Defog as directed on the shield and havent had anymore problems. Others still do, but my racing buddy and I dont have any problems. Thanks!!! Joe

Mask Defog-Not bad - I bought this with my order and used it as well as another brand in Guam. This worked well but you have to be careful not to use too much or it just goops up. Pretty much less is better. The other brand was thinner but I didnt see much difference between them. Overall this works pretty well for the price. The size is pretty large so it will last a long time.

Great fit, awesome visibility - This is my first mask since I was a kid. Best fit ever and I was able to order corrective lenses for a perfect snorkel experience:)
