DETAILS
The harmony of a new Sirmont style.
The perfect blend of the slender plastic brow and the pronounced metal part. The harmonization of the two opposing materials delivers and encourages new audience to Four Nines’ recent design approach.
Front construction which ensures durability.
Despite its front composition based on two different materials, its front durability is ensured by composing the plastic brow based on a metal frame construction. Negative warpage is prevented at the bridge by brazing the bridge to the rim of 1.00mm frontal and 2.8mm lateral view from two dimensions from the frontal and the lateral dimension.
Gyaku-R hinge assembled with functionality.
The improvement of the front durability raises the effectiveness of the Gyaku-R hinge which effectively disperses stress away from the frame preventing deformation. This ideal frame balance creates and sustains the superb comfort.
