SCUBAPRO MASK - FRAMELESS GORILLAThe Frameless Gorilla has a slightly larger and wider lens, 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 as the original Frameless.. 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. Push-button buckles attach to tabs on the skirt to optimise range of motion when dialing in fit. Buckle tabs are flexible, enabling the mask to be folded flat for travelling. Wide headband allows for a comfortable fit against the back of the head.
