The Atomic Aquatics SubFrame distinguishes itself by providing the scuba diver with a great field of vision while being a low-volume, ultra-durable mask. The SubFrame mask is such a strong mask that Atomic Aquatics offers a life-long warranty on frame-breakage.
The subframe has been attached under the silicone skirt, which is a new technology and Atomic Aquatics has a patent pending. The stainless steel retainer keeps everything in place and provided even extra strength.
