East Asian golfer wearing black 2nu sunglasses with green mirrored lenses for the Hiking and Golf sunglasses guide.

Your activity match

Read green-and-brown ground detail across both the trail and the course.

Roots, soil, tree shade, fairway contours, and ball tracking all reward balanced contrast and long-wear comfort. 2nu green-coated options can help separate green-brown detail; compare Hexachroma for flagship clarity with TVO Pro for harder glare.

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.

Green and brown ground detail merges together

Fairway, rough, bunkers and shaded ground can sit within similar tones, making slope and surface changes harder to separate.

How 2nu solves it

Prioritize balanced terrain contrast

Hexachroma is the flagship choice when fairway texture, ball tracking and outdoor detail matter together. TVO Pro is the focused option when controlling reflected glare is the main priority.

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.

Open tee boxes turn into shaded greens

Sun direction and tree cover can change from hole to hole. A very deep tint can make shaded detail harder to read.

How 2nu solves it

Choose for the whole round

Use balanced light control for courses that move between open sun and shade. Deeper configurations suit sustained intense glare, but the best golf lens preserves useful detail across the light you actually play in.

Checking the strongest available matches.

How we choose

Balanced for Hiking + Golf

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.

Golf

Better ball and terrain separation without flattening the greens.

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™ 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.

Cogs: 55-19-138; total width 145 mm.

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.

02Why can a green-coated lens help on fairways and greens?

Fairways, rough, trees and soil sit 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 grass, ground and shaded detail more clearly.

03How can I check hiking fit and comfort before choosing?

Compare frame coverage and head-fit information in the product callout for long-wear support. On a FlexFoam™ frame, adjust it by hand first, then wear it for about five minutes so FlexLock™ can distribute support around the head instead of concentrating pressure at one point.

04Can polarized lenses darken a rangefinder or GPS display?

They can. Screen behaviour varies by display and viewing angle. Hexachroma is the screen-friendlier polarized option and helps reduce common black-out effects, but the result cannot be identical on every rangefinder, GPS, phone or watch.
