This new Scubapro Trufit ultra-soft skirt has been technically-developed to not only fit any-and-every face shape, but also incorporates a unique-rigidity allowing perfect seal and comfort. Rather than consisting of two separate materials, the Trufit skirt has been achieved using two different thicknesses of the same high quality silicone in one skirt, assuring total comfort and sophisticated simplicity. The silicone is thicker and firmer, with a matt finish near the mask frame, providing needed support and rigidity. The silicone contouring the face is thinner, giving a softer-feeling, for a truly unique fit and seal. Trufit technology can be identified by its unique ribbing texture. As with all Scubapro products the Trufit skirt has been tested by demanding divers and improved upon before ever hitting the market. The Synergy Twin Mask is constructed using a new generation Trufit skirt, although first generation Trufit with unique-ribbing and softness can be found on certain Spectra and Volta Models. Try a Trufit mask, and feel the difference. An excellent mask is essential to premium diving adventures. Trufit makes you feel one with your environment, one with your element: water. The Scubapro Synergy Trufit Twin Mask has all the other features you expect on a high quality dive mask. The mask has a double feathered edge skirt and a wide split style silicone rubber mask strap that combine to create a perfect seal on the face. The dual tempered glass lens design allows for maximum underwater vision and the intake of light. Mask is equipped with an easy-to-reach one-hand nose pocket for ear equalization which can be utilized even when wearing thick gloves. The Mask is equipped with easy to adjust swivel buckle system. Its low profile low volume personality means clearing the mask is an effortless task. Because the Trufit mask has two lenses, you'll be able to clearly and easily see more of what surrounds you. The lenses of the mask are made from an ultra-clear mirrored glass. Standard glass has a green tint. The green tint you see is the result of iron impurities left over in lower quality float" or window type glass. That green tint distorts true colors and blocks out some of the light that reaches the eye. Ultra-Clear is a new and exciting optical quality tempered glass with exceptional clarity and high light transmission, with no color distortion. The exceptionally high light transmittance and lack of distortion in the ultra-clear lens maximizes the light available for improved visual acuity, especially underwater in low light conditions, Better vision, truer colors is what you get with Scubapro's Ultra-Clear Lenses. The mirrored lenses also provide protection against glare when on the surface making this one great visual experience for the new to the most experienced divers. The Mask comes with a protective mask box..
