Seasoft Delta Force Frameless Mask w/ SEAVUE Antifog Spray

Quick answer: The Seasoft Delta Force is a light, frameless single-lens mask with Ultra Clear HGG low-iron glass and Crystal ARC anti-reflective coatings. Seasoft designed its skirt for medium-large through extra-large faces, and it comes with the SEA DIAL strap, a soft case and SEAVUE anti-fog spray.

Why bigger divers look at it

Seasoft rates this mask for medium-large through extra-large faces. The FITZ liquid silicone skirt has a flared sealing surface, and the SEA DIAL strap tightens in small steps and spreads tension evenly around the mask, so you can get a seal without cranking the strap. As Seasoft notes, face shape matters as much as size, so still do the fit test below.

What it does well

Seasoft says the lens system lets through up to 98% of available light, compared with about 84% for standard glass. That helps most on night dives, in low light and in poor visibility. The wide, non-slip strap support sits securely on your head or hood without tangling in hair, and the frameless build stays light for travel.

Before you buy

The coated lens needs Seasoft's own preparation before the first dive, and you should avoid any cleaners or prep methods that Seasoft doesn't recommend. The old neoprene clamshell strap cover is no longer included. Hold the mask to your face without the strap and breathe in gently through your nose; it should stay put without pressure at your temples or nose pocket. Read How to Fit a Dive Mask.
