XS Scuba Ethos Mask

Quick answer: The XS Scuba Ethos is a frameless freediving and spearfishing mask with an internal volume of roughly 79 cubic centimeters, one of the lowest available. Ocular Orbit eye cups keep the two lenses aligned, and an adaptive skirt flexes to fit a range of face shapes and sizes.

Why bigger divers look at it

Ultra-low-volume masks usually fit tight and unforgiving, but the Ethos skirt has adaptive flex zones that stretch and contract in both length and width. XS Scuba says that lets it mold to the contours of various face shapes and sizes, which gives a larger face a better shot at a comfortable seal than a typical rigid low-volume design. It still sits very close to the face, so test the fit first.

What it does well

Internal orbital eye cups hold both lenses on the same plane, which prevents visual distortion while keeping volume extremely low. Each eye cup has a channel so it equalizes along with the rest of the mask. The matte black skirt cuts reflections for stealth while hunting. It folds up small, so it also makes a great backup mask for any diver.
