Head fit guide
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.
Dimensions show the shape. Flexibility and contact points also affect fit.

Angular frame
Cogs has a structured, angular frame. Compare the frame dimensions and wearing feel to choose a comfortable fit.
Metonic Coating
Metonic Coating forms a protective layer over the mirrored lens finish and withstands seawater, sweat and oil exposure for 48 hours, helping reduce coating peel-off and delamination. Rinse with fresh water after exposure and dry with a clean microfibre cloth.
FlexFoam™
FlexFoam™ is lightweight and flexible, designed for a comfortable, secure fit. With supported non-prescription lenses, the complete sunglasses float in seawater.
Hexachroma
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.
Frame and lens essentials
Cogs uses a structured angular shape and a lightweight FlexFoam™ frame that is flexible, hand-adjustable and comfortable for long wear. Its non-hollow frame floats in seawater. Current lens options include UV400 protection; recognised lens families on this page are TVO, TVO Pro, Prescription and Prescription Hexachroma. Use the Frame Guide, then TryOn if you still want to confirm fit in movement. Selected non-prescription configurations only.
