With low internal volume, achieved by its award winning frameless design, the 145 Frameless Mask offers the benefits of a double-edged silicone skirt face seal. Fits most standard-size to wider faces and comes standard in a protective storage box with a single-use sample of McNett Sea Buff™ dive mask precleaner and Sea Gold™ mask anti-fogger. Available in black only, which reduces reflection and peripheral glare.
