Built for paddle boards, kayaks, boat days, beach training, and long sessions near open water.
Strong glare, wet movement, dropped sunglasses and seawater residue can all affect how clearly and comfortably you see. Turn each card to see how 2nu addresses it.

Reflections from water, wet decks and pale sand can hide changes in distance, obstacles and surface texture.
TVO Pro controls strong reflected glare. Choose flagship Hexachroma when you also want more outdoor detail and better readability on phones, watches and other screens.
Sweat, spray and repeated movement can make sunglasses shift. Simply tightening the temples can create pressure at the nose and sides of the head.
Adjust FlexFoam™ by hand to suit your head, then wear it for about five minutes so the fit can stabilise. Every FlexFoam™ frame includes FlexLock™; its wraparound design distributes pressure around the head instead of relying on one tight contact point.
During watersports, ordinary sunglasses can sink before you have time to recover them.
Its non-hollow construction does not rely on air trapped inside a hollow frame. Complete-pair buoyancy still depends on the lens configuration, and Prescription versions are not covered by the non-prescription floating claim.
Salt, sweat, sunscreen and oil can build up during a day on the water and affect the lens surface and clarity.
Every 2nu sunglass lens includes Metonic Coating. Its protective layer withstands seawater, sweat and oil exposure for 48 hours, helping reduce mirror-coating peel-off and delamination during repeated watersports use. Rinse with fresh water after use and dry with a clean lens cloth.
Both are polarized. TVO Pro is focused on controlling strong reflected glare. Choose flagship Hexachroma when you also want higher contrast, more outdoor detail and better screen readability. Choose for the conditions rather than simply selecting the darkest lens.
FlexFoam™ uses a non-hollow floating frame material. With non-prescription lenses, the complete pair floats in seawater. Prescription lenses are heavier, so Prescription versions do not float. For the strongest flotation performance, choose eyewear carrying the FlowMax label.
Adjust FlexFoam™ by hand to suit your head, then wear it for about five minutes so the fit can stabilise. It should feel secure without concentrated pressure at the nose or sides of the head. Every FlexFoam™ frame includes FlexLock™, whose wraparound design helps distribute pressure around the head.
Rinse the sunglasses with fresh water after use, then dry them with a clean lens cloth. Metonic Coating forms a protective layer over the mirrored finish and withstands seawater, sweat and oil exposure for 48 hours, helping reduce coating peel-off and delamination. Regular care is still required.
