Fourth Element Aquanaut Freediving Mask

Quick answer: The Fourth Element Aquanaut is a low-volume freediving mask with a new skirt design developed to fit as many face shapes as possible. It offers a surprisingly wide view for its compact size, comes with a clear or Contrast lens, and ships in a zero-plastic protective case.

Why bigger divers look at it

Fourth Element designed the Aquanaut's soft silicone skirt as a universal fit, aiming to suit as many faces as possible with one design. That makes it a better bet than most compact freediving masks if your face is on the broader side. It's still a low-volume mask that sits close, so do the fit test below. The molded silicone strap can be swapped for Fourth Element's 100% recycled strap, sold separately.

What it does well

It's a capable all-purpose mask, not just a freediving mask, thanks to its wide field of vision. The Contrast lens filters some mid-range wavelengths of visible light and has a green/blue tint. Fourth Element also cut out plastic packaging entirely.

Care note

Rinse in warm fresh water after diving to dissolve salt, towel dry completely, and never use abrasive cleaners on tinted or coated lenses.

Before you buy

Hold it 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. More options: Wide-Fit Scuba Masks for Larger Faces.
