J.F. Rey: SLEDGE Series – The Mechanics of Style
Thursday, March 26 2026 | 08 h 42 min | Fashion Frames
J.F. Rey is continuing to build on its SLEDGE series, a collection the company positions as a showcase of its expertise in eyewear engineering and structural design.
The series takes an architectural approach in which technical refinement is not only functional, but also central to the visual identity of the frame. J.F. Rey describes the collection as one where structure itself becomes a defining design element.
At the core of the concept is a patented hinge system that rethinks one of the frame’s essential components. The screwless Flex mechanism is integrated directly into the temple and is designed to combine flexibility, durability and a clean, minimalist look.
The collection is offered in titanium, acetate and hybrid constructions. Materials used across the series include Grade 5 titanium, surgical stainless steel, carbon fibre and plant-based acetate. The result is a range of frames designed to be lightweight, durable and comfortable to wear.
The brand also points to a metallic detail within the design that emphasizes the Flex function while adding visual contrast through the use of bold colours and satin-finished titanium.




Originally launched in 2023, the SLEDGE series continues to evolve with each season, serving as an ongoing platform for the brand’s exploration of the relationship between technical performance and aesthetic expression.
