NAVIGATOR MASK CLASSIC FIT

The Fourth Element Navigator is a twin-lens dive mask built around recyclability as well as fit. The silicone skirt and the moulded silicone strap are both fully recyclable, which is unusual in a category where masks are normally a mix of bonded materials.

The lenses are tempered glass in a twin-lens frame, which gives a wide field of vision and allows corrective lenses to be fitted later. Two lens options are offered: a clear glass lens that passes the maximum available light, and the Enhance lens, which filters ultraviolet and high-energy visible light to protect the eye and lift colour separation. The mask is made in Taiwan.

The result is a mask that suits a diver's face rather than a marketing brief. The Classic Fit is the narrower of the two facial shapes Fourth Element offer, and choosing correctly between it and the Wide Fit does more for a leak-free dive than any lens or skirt technology.

Two variants, both black-skirted, with a clear lens or the Enhance lens. The Wide Fit is the same mask on a broader face shape. The Fourth Element recycled Mask Strap fits it directly. The Seeker is the frameless single-lens alternative and the Scout the fully configurable one.
