The Scubapro Synergy is a twin lens mask that uses Scubapro's new Tru Fit skirt technology which implements varying silicone thickness & strength to offer enhanced fit, comfort & seal. The Synergy Twin mask uses a minimal frame construction to reduce the overall size, profile & weight of the mask. The remaining thin frame is finished in a variety of two tone colours. The lens uses the now common practice reverse teardrop shape to ensure a wide horizontal field of view & increased lower visibility. The frame & lenses are also raked in at the bottom to move the lower frame out of visibility & allowing better sight of equipment when looking downwards. The Tru Fit skirt uses two different thicknesses of a high quality silicone, a thicker & firmer section near the frame to provide strength & rigidity & a thinner section near the face to provide a softer feel & better seal. The skirt features a large number of thicker ridges around the top & sides of the skirt that are designed to resist buckling & deformation of the skirt during normal use.
