Cressi Antifog 60 Ml
I ve been snorkeling for 16 years and always had a problem keeping my mask clear. I found this product in a local dive shop in Aruba. This kept my mask clear for over and hour of snorkeling. It is the best I ve found.
The best thing you can say about this product is that, it works and works well.
I have bought it second time and can recommend. Works as designed ;)
i´ve tried and it works
I tried it and it works, I have to go back to spray whenever you use glasses or every 2 times. I have not tried other brands.
