Vintage design: reproducing the classic symbols of the golden age Metal frames are a mark of time Adopting the classic silhouette of aviator/round/square frames, inspired by the nautical and outdoor equipment of the mid-20th century, the metal front frames are made of stainless steel/titanium alloy, with matte plating surface treatment, presenting vintage tones such as antique bronze, gunmetal grey, silver blue, etc., and with fine texture of the edges, which brings a sense of high quality with the precipitation of the years. Carved details on the temples: the metal temples are engraved with vintage totems (such as anchors, knots and other nautical elements) or brand logos on the outside, the model number is laser engraved on the inside, and spring hinges are used at the opening and closing points, which combines vintage modelling with modern practicality, and is a good fit for wearing and does not pinch the head. Balanced aesthetics between vintage and functionality Wide rimmed frame design: larger lens area, enhanced side shading effect, reducing water reflection from the side, while creating a retro atmosphere; Removable leather leg covers (optional accessory): some models come with leather leg wraps, which enhances the retro style and increases the friction to prevent slipping, suitable for long time rod holding position. Fishing Scene Exclusive Function: Be the invisible hunter on the surface of the water. Polarised lenses: See-through eyes that penetrate the water. Equipped with C-POLARIZED professional polarised lenses, the optical-grade PET polarised layer can filter 98% of the glare on the surface of the water, clearly presenting the structure of underwater fish, undercurrents, and obstacles, allowing anglers to accurately judge the timing of bites and the choice of fishing spots. Preferred lens colours: Teal lenses: Enhance contrast and reduce glare, suitable for cloudy or early morning/evening light, reproduces true colours; Dark grey lenses: Highly concentrated blackout to cope with midday light or snow reflections, maintaining neutral tones and preventing visual fatigue.

Impact-resistant PC lens substrate: Passed the ball impact test (16g steel ball falling from 1.27 metres without cracking), to deal with fishing line flinging, fishing gear collision and other accidental scenarios, safe and reliable. Metallic material: Durability and wearing experience are both upgraded. Hardcore metal structure Aviation-grade stainless steel / titanium alloy material: weight only 28-32g (measured data), 30% lighter than traditional copper alloy, corrosion-resistant, bending-resistant, even in contact with seawater, sweat is not easy to oxidise and fade, suitable for all-weather outdoor environment. Electroplating process: The surface is 5 layers of vacuum ion plating, anti-scratch and wear-resistant, and still maintains the metallic luster even after long-term use, refusing to be embarrassed by paint loss. Ergonomic Details Silicone nosepiece + non-slip end of the temples: The nosepiece can be adjusted to fit different nose shapes; the end of the temples has built-in silicone particles, so that it is not easy to slip off when holding the rod with your head tilted back, so that you can concentrate on fishing without being distracted.
