Koah Frameless Mask

Overview

The Koah Frameless Dive Mask is a low-volume mask for freediving, spearfishing, snorkeling, and recreational diving. Its close-set lens and flexible frameless construction keep the profile compact while supporting broad underwater visibility.

Design and use

Positioning the lens close to the eyes reduces the internal air space, supporting easier mask equalization during descent. The same close-set geometry expands the field of view, improving peripheral awareness around fish, reefs, other divers, and nearby equipment.

Without a rigid outer frame, the mask can flex and pack with less bulk. The soft silicone skirt conforms to the face while the adjustable strap secures the fit. Because sealing depends on face shape, the skirt should sit evenly against the skin without gaps before entering the water.
