The clear frame of this four-window mask lets in maximum light for the most exhilarating visual experience in diving. Excellent for diving in low light waters, and everywhere else. Absolutely the lowest volume four-window purge mask. Low-profile purge for hands-free clearing and exposed nose pocket for easy one-handed equalization. Extra thick long lasting silicone skirting. Cue Strap included.

Cue Straps are patented mask release buckles on every XS Scuba M Line mask. Soft neoprene pads prevents tangling. Nonskid backing prevents buckle-slide. A well-fitted, totally integrated mask makes your dive so much more satisfying.

The purge valve is a standard feature on all Ocean Master masks. With a simple exhale all water is cleared from the mask. Located at the lowest point of the mask, the purge valve ensures that water is cleared out completely. The new and improved purge cover helps to direct bubbles away from the face.
