Scuba Diving

I have been scuba diving for over 40 years and have spent a lot of money on head gear for scuba diving in warm waters that did not work. They would fill up with air and bubble, or slip off of my head. Just used your product on an extended diving trip and it worked better than anything else that I have tried, it is in my experienced opinion your product is the best warm water scuba diving head gear in the world, bar none.
