We are living in Bermuda and we bought these vests primarily for visitors who come and want to snorkel but are not entirely comfortable in the water. It serves the purpose. Our guests feel more comfortable, and we actually feel better knowing that, if we had to, we could blow up the vest and easily float a fatigued snorkeler to shore.

We are generally snorkeling in calm waters, so if I were to do it over again, I'd probably get the "reef" vest versus the "current" vest. The main problem with the vest is that it is quite large and a bit stiff. Even for people who wear an x-large or xx-large t-shirt, the vest was big. You may find that the youth size is adequate for some adults. The material is stiff and can bother the neck when inflated. On that note, when fully-inflated, the vest can be uncomfortable on the neck.

Finally, the vest states right on it that it is not a life-saving device, so I just mention that in case the product description does not.

Bottom line is that it does what we need it to do, but if I were to wear a vest every day for snorkeling, I'd probably try to find one that's softer and a better fit.
