Absolutely needed a own snorkeling with a diving mask for my first snorkeling vacation in Egypt. Since I was uncomfortable with the thought that you could borrow it in Egypt is locally. It was indeed an effortless process, but considered hygienic, absolutely iiii ... Therefore I decided to buy this and do not regret it. Every day I could easily look at the underwater world. Only when laughing was water in the glasses. But normally, as this creates "wrinkles", which could penetrate the water.
Purchase worthwhile and attracts a lot of envy. = P
