Fancy™ Sunglasses
FFMBKOE-TRegular price $169.00 AUDRegular priceUnit price perExplore the fit
Fancy™ — Frame dimensions
Loading your frame…
Overall width—mmFront-to-back length—mmStraight horizontal spans with temples open. Front-to-back length is not temple length.
Head fit guide
Size - Normal is the standard 2nu fit class for most everyday head shapes. Fancy gives a classic standard-frame feel, while Zealot gives more front coverage but still sits in the normal fit direction.
Dimensions show the shape. Flexibility and contact points also affect fit.
UV400 protection blocks UVA and UVB rays up to 400 nm, the range most relevant to daily outdoor sun exposure. It is the baseline protection in 2nu sunglasses, so your eyes are protected while the lens technology handles glare, contrast, and comfort.Polarized lenses reduce strong reflected glare from water, glass, wet roads, and other bright surfaces. They are useful outdoors, but typical polarized lenses can sometimes make phone, watch, dashboard, or navigation screens black out or look uneven.Hexachroma™ is 2nu’s outdoor light-management lens technology. Typical polarized lenses mainly reduce glare from one direction. Hexachroma™ is tuned to manage more complex outdoor reflections from seawater, wet roads, metal grates, glass, and concrete, reducing harsh glare while keeping road texture, water layers, shadow detail, and colour contrast easier to read. The goal is not to make everything darker; it is to keep vision clearer, steadier, and more natural outdoors.Metonic Coating forms a protective layer over the mirrored lens finish. It withstands seawater, sweat and oil exposure for 48 hours, helping reduce coating peel-off and delamination and improve durability during repeated outdoor use.FlexFoam™ is 2nu’s flexible frame construction for comfort and stability. It gives the frame a more forgiving feel against the head and face, helping reduce pressure during long wear while keeping the sunglasses secure for outdoor movement.FLOAT MAX is built for water use. The frame is designed to stay afloat if dropped in water, helping reduce the chance of losing your sunglasses during paddling, boating, beach training, fishing, or water sports.Prescription lenses are made to order from your vision details. Choose the frame and lens option first, then enter your prescription at checkout or send it later by WhatsApp or email. Production starts after the details are confirmed. -
