IST Hunter Anti Fog Mask

Quick answer: The IST Hunter Anti Fog is an extremely low-volume mask with a built-in anti-fog lens film, tempered glass, a non-reflective matte skirt and swivel easy-adjust buckles. It's built for spearfishing, freediving and underwater photography, and works well for scuba and snorkeling too.

Why bigger divers look at it

The high-grade silicone skirt is soft for a comfortable seal, and the swivel buckles let you make quick, precise strap adjustments so you can seal without over-tightening. IST doesn't publish a face-size rating, and low-volume masks sit close to the face, so test the fit first. If you prefer a big panoramic mask with lots of room, this compact design isn't the one.

What it does well

Fogging is one of the most annoying problems in diving, and the Hunter tackles it with an anti-fog lens film so you're not reapplying defog before every dive. Low internal volume makes clearing and equalizing easier. The matte skirt cuts reflections that can spook fish or show up in photos.

What you get

• Integrated anti-fog lens film
• Extremely low internal volume
• Tempered glass lenses
• High-grade silicone skirt with a matte, non-reflective finish
• Swivel easy-adjust buckles

Care note

Before first use, remove the matte protective film from the inside of the lenses as IST instructs, and rinse the mask in fresh water before each dive. Follow IST's care directions to protect the anti-fog film, and avoid abrasive cleaning.

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.
