Hiker wearing 2nu sunglasses on a forest trail for the Hiking and Water Sports sunglasses guide.

Your activity match

Move from forest shade to shoreline glare without losing trail detail or wet-use stability.

Changing trail light, wet rock, open-water reflection, and seawater residue make this more than a generic outdoor pair. Hexachroma supports map or phone checks and mixed detail; TVO Pro targets hard water glare, while Metonic helps resist seawater, sweat, and oil.

The four issues that matter most across your two activities

We selected two high-priority issues from each activity. Open any card to see how 2nu addresses it.

Green and brown merge together

Leaves, soil, tree trunks and trail shadows sit within similar green-brown tones. A lens with a similar colour balance can flatten the terrain into a monotone scene.

How 2nu solves it

Green outside, balanced contrast through the lens

From the outside, the coating looks green; through the lens, the view leans violet-red. This helps separate greens, browns and shadow detail for a more balanced trail view. It applies to all green-coated TVO, TVO Pro and Hexachroma lens options, including green-coated Prescription and Prescription Hexachroma options.

Glare hides changes on the water

Reflections from water, wet decks and pale sand can hide changes in distance, obstacles and surface texture.

How 2nu solves it

Choose polarized control for the conditions

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.

From forest shade to an exposed ridge

One trail can move quickly between deep shade and strong open light. A lens that is too dark can hide roots and surface detail under tree cover.

How 2nu solves it

Balance shade and open light

Hiking is not about choosing the darkest lens. 2nu recommends balanced light control based on the amount of tree cover and exposed terrain, keeping open sections comfortable without losing too much detail in the shade.

Wet movement can shift the frame

Sweat, spray and repeated movement can make sunglasses shift. Simply tightening the temples can create pressure at the nose and sides of the head.

How 2nu solves it

Adjust first, then let the fit settle

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.

How we choose

Balanced for Hiking + Water Sports

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.

Hiking

Clearer terrain contrast with comfort from sun to shade.

Water Sports

Strong-light control with secure, water-ready performance.

Lens

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.

Questions before you choose

Use these answers to compare the lens, frame and conditions that matter across your selected activities.

01Should I choose Hexachroma or TVO Pro for hiking?

Choose Hexachroma when flagship terrain detail, changing-light clarity and easier phone or GPS checks matter most. Choose TVO Pro when strong polarized glare control on exposed ridges, wet rock or water is the main priority.

02Does every FlexFoam™ pair float in seawater? What about Prescription versions?

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.

03Why does 2nu recommend green-coated lenses for hiking?

Hiking scenery is dominated by foliage, soil, trunks and shadows within similar green-brown tones. A green-coated 2nu lens looks green from the outside but gives a violet-red-leaning view through the lens, helping separate greens, browns and shaded trail detail. This colour balance is available across green-coated TVO, TVO Pro, Hexachroma and green-coated prescription options.

04How should I adjust FlexFoam™ before watersports?

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.

Move from forest shade to shoreline glare without losing trail detail or wet-use stability.
