The 145 Frameless Mask has a revolutionary design that increases underwater field of vision up to 28-percent. A large, teardrop shape lens increases peripheral and vertical vision. 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. Available in black only, which reduces reflection and peripheral glare.
