The SYNERGY TWIN TRUFIT benefits from SCUBAPRO’s second-generation Trufit technology. This design approach features a mask skirt with thicker, firmer silicone near the mask frame to provide support and rigidity, and thinner silicone contouring the face for comfort and to ensure a watertight seal. It’s an effective combination that delivers a truly unique fit and seal. In addition to comfort, the SYNERGY TWIN TRUFIT’s dual lens design is low volume and provides excellent field of view, and its buckle and strap system is easy to use. The rotating buckles attach to tabs on the skirt rather than on the frame. This optimizes strap angle and range of motion when dialing in fit, plus it enables the mask to be folded flat for easy packing.
