The front is made of a single piece of sheet metal with 1.4 mm-thick titanium endpieces soldered onto it to meet structural strength requirements. The outset-style beta-titanium temples provide both a comfortable fit and the rigidity needed to maintain the frame’s form over time. The temple ends, which have a good grip and are molded from CP and silicone, are combined with end tips made of tungsten, which means heavy stone in Swedish and has a very high specific gravity, to reduce the weight on the front and bridge of the nose. We pursued the ideal product that is comfortable to wear, lightweight, and durable. The sunglasses lenses are made of CR39, a material that offers both lightness and durability. With a light tint *30–40% transmittance and double-sided anti-reflective coating, they are designed for comfortable wear from day to night. Paired with the high-spec frame, they embody functional versatility for everyday use.
