Sherwood would like to say that the Spectrum Mask is one of a kind. But with three completely different lenses, it's simply not true. With the Sherwood Spectrum Sherwood is introducing their first Mirrored and Colored Lens Mask. Each color provides a unique perspective above and below the surface. Mirrored and colored lenses not only provide a new and refreshing look to a standard tempered lens, they also enhance the lens functionality. The Sunscape lens is designed for diving where colors are vibrant. This unique lens will filter out blue wavelengths which allow more reds, yellows, oranges and greens to your eyes while diving. The Rubicon lens is designed to add more optical contrast and make things easier to spot while diving. The Platinum lens is designed to reduce the glare from sun while at the surface, without compromising visual acuity, while below the surface.All three versions of the Spectrum Mask has a high quality silicone rubber double feathered edge skirt and wide split head strap that combined for a perfect seal on the face. Adjusting the mask strap is made easy with the pivot buckle/strap assembly. The ergonomic nose pocket is an easy-to-reach one-hand nose pocket for ear equalization which can be utilized even when wearing thick gloves. The dual reversed teardrop tempered glass lenses provide crystal clear vision. The mask is available with a black mask skirt. Mask comes with a mask box.
