If you’re trying to decide between the two the Gill mask Pro is the clear winner for breathability. I’m very pleased with it.
Pretty bad fit
I think the overall components of the mask felt like it was good quality. But the lack of a wire on the nose bridge, couple with soft silicone used meant that exhaled air was escaping through the top of the mask. Regardless of how tightly it was worn. This meant that air would constantly be exhaled straight to the eyes. Couldn't wear it for more than a couple of minutes.
