Finally, the M3 Dive mask from Hollis has arrived! And yes it does seem to be worth the wait - not only does it have the Ultra Clear glass and super soft silicone but the glass at the bottom of the lens comes so close to your face that it almost touches it giving you an amazing downward viewing angle for gauges and camera gear.
The Hollis M3 low profile design uses a rigid frame and two lenses with an extra clear glass which is valued for its attractive appearance and optical qualities. The low iron content produces a higher light transmittance and a reduced green tint inherent in other glasses. This makes the lens distortion free and helps improve colour and visibility in low light conditions underwater.
Prescription Lenses can also be fitted into the M3.
