Your activity match
Open water and snow both throw hard reflected light, while the frame must also handle seawater residue, exposed terrain, and long route checks. Keep UV400 and polarized glare control central; compare Hexachroma for screens and detail with TVO Pro for hard glare.
We selected two high-priority issues from each activity. Open any 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.
Above the treeline, direct sun and reflected light can remain intense for long sections with little natural shade.
Every 2nu sunglass lens provides UV400 protection. For sustained exposed glare, start with the deeper blue- or gold-mirror configurations that rank strongly on the ALPINE axis, then choose TVO Pro or Hexachroma by detail and screen needs.
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.
Terrain can move from bright snow or pale rock into deep shadow, making surface texture and route cues harder to separate.
TVO Pro focuses on strong polarized glare control. Hexachroma is the flagship option when you also want higher outdoor detail and easier separation across exposed and shaded terrain.

How we choose
We compare brightness and changing light, colour and contrast, reflected glare and screen use, and frame performance across both activities—then rank the strongest overall balance.
Strong-light control with secure, water-ready performance.
Stronger light control and coverage for exposed high-altitude conditions.
Use these answers to compare the lens, frame and conditions that matter across your selected activities.
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.
Above the treeline, direct sun and reflected light can remain intense for long sections with little shade. Deeper blue- or gold-mirror configurations are the starting point for sustained exposed glare; compare the ALPINE radar and the exact lens option rather than choosing by colour alone.
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.
They can. Screen behaviour varies by display and viewing angle. Hexachroma helps reduce common polarized screen black-out while retaining glare control, but the result cannot be identical on every device. Check essential route tools before a long trek.
