The snorkel mask is built with quality materials. The glass is totally anti fog and allows a clear and wide angle view. The two bands that keep the mask on the face are really comfortable, as well as the gasket that allows to wear the mask for long time without any problem. The knob for the action camera is another plus, really appreciated. In conclusion, a very high quality mask for an affordable price
Ok, so I'm not a huge snorkeler to begin with but I this was had to get used to. I'll keep trying. I like being able to breathe through my nose but it's an adjustment.
