FAQs

Is the Genesis Sigma a frameless mask?
Yes. The Sigma uses a compact frameless design that reduces unnecessary bulk and internal volume.

Does the Sigma have one lens or two?
The Sigma features one large, wide-view single lens.

What is the benefit of a low-volume mask?
A lower internal volume generally requires less air to clear the mask and can make pressure equalization easier as you descend.

Does the mask have adjustable buckles?
Yes. The Sigma features an easy-adjust strap with quick-connect and disconnect swivel buckles.

Care & Maintenance

Rinse the mask thoroughly with fresh water after diving, especially after exposure to salt water or chlorine. Allow it to dry completely before storage and avoid prolonged exposure to direct sunlight or excessive heat. Periodically inspect the silicone skirt, strap, buckles, and lens for wear or damage.
