I bought this mask based on the manufactures description and few, but positive reviews. I am very glad that I did. Great value for the money. The mask has a very rugged design, quality construction. Solid outer frame with stainless bolts mounted to a very soft comfortable, well shaped skirt that seals perfectly. The rigid lens frame has pivoting buckles to attach the straps, that creates a nice even pressure for good seal around the face and upper lip, where my masks usually leak. First time out, I wore it for 45 minutes, very comfortable, no issues. Visibility is very good as well. Very satisfied with this mask. I know it was designed to be rugged, it functions very well.
