Tusa Freedom Tri-Quest Mask

Quick answer: The TUSA Freedom Tri-Quest is a panoramic mask with a one-piece front lens flanked by TUSA's patented domed side windows, for three windows in all. A slimmed-down frame cuts blind spots, Freedom Technology helps the skirt seal, and a 3D strap with a five-position angle adjustor dials in the fit.

Why bigger divers look at it

The five-position strap angle adjustor is the fit feature to know about: you choose where the strap meets the back of your head instead of living with one fixed angle, which helps if a standard strap rides up or digs in. TUSA's Freedom Technology is designed to adapt the skirt to your face, and the 3D strap follows the curve of the head. TUSA doesn't publish a wide-face size for the Tri-Quest, so do the fit test below.

What it does well

The single front lens means no center bar in your view, and the domed side windows pull in light and peripheral vision so the mask feels open rather than boxed in. TUSA trimmed the frame structure specifically to reduce blind spots, which is a big part of why panoramic fans like it.

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.
