Barracuda DeFogger is a laboratory tested, non-irritating solution balanced to the same PH as the human eye. Assures clear vision. Great for defogging goggles, glasses, scuba masks, and other eyewear. Apply Barracuda DeFogger to improve visibility when swimming.
I've tried all defoggers and find Barracuda is the only one that works 100 percent all of the time.. The only problem is that it isn't available in any stores and has to be purchased on line. That incurs a shipping charge that is exorbitant compared to the price of a bottle of defogger.
It works well when I have practice for 2-3 hours.
