Scubapro’s Synergy Twin is an all-purpose dive and snorkel mask with a special skirt that seals instantly and securely to a wide range of face shapes. The skirt uses Trufit technology, which is a soft, high-grade silicone that’s shaped thicker at the base and then tapered to a flexible edge. It’s reinforced with ribs for support yet still conforms to the natural curves of the face. Twin lenses sit inside a rigid frame. Their tear-drop shape yields a better downward view, so divers can more easily see gear and gauges attached to their BC. Quick-adjust buckles mounted directly to the skirt provide flex for comfort but also allow the mask to be folded flat for easy carrying. The Bottom Line: With its soft, tapered skirt, the Synergy Twin focuses on fit so divers can focus on everything else.
