This is the ScubaPro Frameless Gorilla Scuba Diving Mask Matte SiliconeFeatures: Extra-large single lens provides an expansive field of view while reducing volume. Slightly larger double-seal matte skirt creates a comfortable, watertight seal on larger faces. Traditional buckles attach to the skirt, enabling the mask to be folded flat for traveling. Wide headband allows for a comfortable fit against the back of the head. The FRAMELESS GORILLA has a slightly larger and wider lens than the original Frameless mask, and a slightly larger skirt in a matte finish. Otherwise, it shares the same classic single lens design and long list of comfort and performance features. Like on the original Frameless, the soft silicone skirt on the FRAMELESS GORILLA is comfortable yet durable, and the double-edge seal feels good against the skin. The buckle system is easy to use and allows for quick adjustments. Buckles attach to flexible tabs on the skirt; this optimizes strap angle when dialing in fit. The wide headband spreads the load on the back of the head, greatly enhancing comfort. For divers with larger or wider faces the FRAMELESS GORILLA is an excellent choice. "
