Gear Aid SEA DROPS 1-1/4 oz Bulk

Fog city

(Used in Swimming pool) I've tried 3 different versions of fog repellent including one from US Divers and my lenses fogged up within minutes. Finally, in desperation, I tried toothpaste and it worked. // So, what commercially available product works? A ten year old bottle Sea Drops with heavy viscosity still works. They must have changed the formula.
