This season's theme for White Mountaineering, "Post De Stijl," is an attempt to deconstruct the primary color norms, starting from the order and abstraction of De Stijl, and reconstruct them into a monotone composition of black, white, beige, green, and purple.
Embodying the philosophy that "design follows function" into contemporary functional wear, by suppressing colors, the brand pursues essential products that adhere to form, proportion, structure, and the movement of the body.
In response to this theme, the WM-01 / WM-01 S was born as a special model with a redesigned front, based on 999.9's NP (Neo Plastic) series. The NP series is 999.9's unique category that overcomes the weaknesses of conventional plastic frames, such as strength and adjustability, by incorporating metal mechanisms and functional parts into plastic frames. This model reconstructs the visual aspect based on its structural characteristics.
The front uses 6mm thick acetate fabric. After three-dimensional cutting by machining, the corners are rounded by cutting, and then carefully polished to create a form that embodies softness within a voluminous presence. The temple core metal and its base are decorated with a motif of White Mountaineering's WM mark, making the structural details even more prominent through the translucent fabric. In terms of functionality, 999.9's iconic unique mechanism, the "Gyaku-R hinge," absorbs the load applied during use. This prevents deformation and ensures a comfortable fit for a long time.
The lenses used for the WM-01 S sunglasses are treated with double-sided hard coat, double-sided water-repellent coat, and anti-reflection coat on the back. The density (35%, 50%, 80%) and color (blue, green, smoke) are combined to match each frame color.
