Three things that matter

Floating first. Then comfort and fit.

Floats in seawater

The non-hollow frame is designed to stay on the surface if it slips off near the shore, board or boat.

Ultralight comfort

Less frame weight through long outdoor sessions, heat and repeated movement.

Adjustable by hand

Fine-tune the temples for a secure fit without hard pressure points.

Choose the floating setup

Fancy: 53-20-138; total width 142 mm.
Zealot: 60-18-138; total width 145 mm.
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.
Both use flexible frame structure to stay comfortable if your face is slightly wider than average.
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™

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.

Halo: 56-18-138; total width 142 mm.
Normal - Smaller is a compact and secure fit for standard to narrower faces. It is useful if regular sunglasses often feel slightly loose, or if you prefer a closer fit for movement.
The FlexFoam™ frame helps the fit feel secure without feeling hard or sharply compressed.

Cogs: 55-19-138; total width 145 mm.
Normal - Larger is a relaxed fit for standard to slightly wider faces. Choose it if regular sunglasses often press at the temples, feel too narrow, or sit too close to your eyes.
Cogs gives a little more room while the soft frame material helps reduce pressure marks during long wear.

Ovo: 57-19-138; total width 149 mm.
Size - Larger / Wide Fit is for wider faces or larger head circumference. It is the safest direction if regular frames often feel tight, pinch at the temples, or create headaches after longer wear.
Ovo gives 2nu’s widest frame structure while the flexible material helps the frame sit more naturally.

FAQ

FlexFoam™, clearly explained.

Three practical answers before you choose your frame and lens setup.

What is FlexFoam™?

FlexFoam™ is 2nu’s non-hollow, lightweight and flexible frame system. It can be adjusted by hand and is designed to float in seawater.

Is Floatanium the same as FlexFoam™?

Yes. Floatanium was the earlier name for the same frame technology. FlexFoam™ is the current name.

Does every FlexFoam™ setup float the same way?

No. Standard non-prescription FlexFoam™ configurations are designed for seawater buoyancy. Hexachroma options marked FLOAT MAX provide 2nu’s strongest floating performance. Prescription lenses add weight and can affect buoyancy.
