IST Syklops Lens Aluminum Mask - Black with Black Silicone Skirt

Quick answer: The IST Syklops is a single-lens mask built in a 6000 series marine-grade aluminum frame. A super-clear tempered glass lens gives a wide field of view, a supple hypoallergenic liquid silicone skirt makes the seal, and the buckles mount directly on the skirt so it packs down small, which tech divers like for a backup mask.

Fit note for bigger divers

IST doesn't publish a face-size rating for the Syklops. The hypoallergenic liquid silicone is soft and kind to sensitive skin, but do the fit test below, and if you have a wide face, compare it against our wide-fit masks.

What it does well

Aluminum gives it a tough, premium build, and the wide single lens opens up your view with no center bar. Skirt-mounted buckles let the mask store very compactly, so it's a natural spare for tech dives or travel.
