I ordered 3 different scuba masks on Amazon. After trying them on I am keeping only one of them. I miss the return window for this so I am selling it on Poshmark. Manufacturer description: Expansive View, Watertight Comfort Trinidad 3 Dive Mask Combining SCUBAPRO's Ultra Clear lens with a frameless, single-lens design, the Trinidad 3 dive mask provides an uninterrupted field of view of the undersea world in a compact, lightweight package. The low-volume design also makes clearing water from the mask easy The mask's quick-release buckles attach to tabs on the skirt to optimize range of motion when dialing in the perfect fit, and they're compatible with SCUBAPRO's optional Comfort Strap (sold separately.) Ultra-Clear Lens Featuring SCUBAPRO's Ultra Clear lens, the Trinidad 3 provides exceptional clarity under water without the greenish tint of normal glass. Additional Features Quick, one-handed buckle system for easy fit adjustment
