The OBD 1St Proteus Mask has large field of vision compared to many other masks. But despite this, the internal volume remains small because the lenses are brought closer to the eyes.

The strap buckles are attached directly to the bezel of the lenses (not the frame, unlike some designs). So the strap will not interfere with the seal of the skirt onto the face. This is especially important when it comes to people with wider facial profiles.

Has a soft black silicone skirt, split silicone strap and easy-adjust buckles. Exellent mask for freediving and spearfishing.
