Angler wearing blue mirrored 2nu sunglasses while fishing on open water for the Running and Fishing sunglasses guide.

Your activity match

Run early, cast for hours—choose for sweat first and reflective water next.

Cadence and sweat test frame stability before a long fishing session adds water glare, line checks, and wet hands. Hexachroma suits frequent watch, phone, or device checks; TVO Pro prioritises bright-water glare, with confirmed floating FlexFoam™ options for seawater use.

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.

01

Slipping—or clamping too hard

Sweat and movement can make sunglasses shift. Tightening the temples too much only concentrates pressure around the nose and sides of the head.

How 2nu solves it

FlexFoam™ + FlexLock™

Adjust the soft, lightweight FlexFoam™ frame by hand first. After about five minutes of wear, it settles into a more stable fit around your head shape. Every FlexFoam™ frame includes FlexLock™, an ergonomic wraparound design that distributes holding force around the head instead of concentrating it at the nose and temples.

02

Surface glare hides line and water detail

Strong reflections can hide fishing line, floats and movement near the surface, while making long periods of observation more tiring.

How 2nu solves it

Use polarization to control reflected glare

TVO Pro controls strong surface glare. Choose flagship Hexachroma when you also want higher contrast, more outdoor detail and better screen readability.

03

Too dark when the route changes

A city run can move from direct sun into building shade, tree cover or cloud. A very deep tint can make darker sections harder to read.

How 2nu solves it

Balanced shade for changing light

For mixed-light routes, 2nu recommends balanced light control rather than simply choosing the darkest lens. Deeper configurations remain useful under sustained intense glare, but mixed-light running needs enough visibility in the shade.

04

Polarized lenses can darken screens

A fish finder, phone, camera or watch can appear dark at certain angles through some polarized lenses.

How 2nu solves it

Hexachroma keeps screens easier to read

Hexachroma maintains polarized glare control while helping reduce the common screen blackout problem. Results still vary by screen type, polarization direction and viewing angle.

How we choose

Balanced for Running + Fishing

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.

Running

Stable through movement and comfortable as light changes.

Fishing

Reflected-glare control and clearer detail over long hours.

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 running?

Choose Hexachroma when flagship outdoor detail and easier watch, phone or GPS checks matter most. Choose TVO Pro when strong polarized glare control is the main priority. Both provide UV400 protection and suit bright outdoor running.

02Why can polarized lenses darken a fish finder, and how does Hexachroma help?

The polarization direction of a screen can interact with a polarized lens, making the display look darker at certain angles. Hexachroma helps maintain screen readability better than many polarized lenses while still controlling glare. Screen type and viewing angle will still affect the result.

03How dark should running sunglasses be for city, cloudy and bright routes?

For routes that move between sun, building shade, tree cover and cloud, choose balanced light control that keeps shadow detail visible. A deeper lens suits consistently bright, exposed routes, but it is not automatically the best choice for mixed-light running.

04Can Prescription fishing sunglasses float in seawater?

Prescription compatibility depends on the frame, prescription power and PD. Prescription lenses also change the weight and buoyancy of the complete pair, so they are not covered by the non-prescription floating claim. If floating performance is essential, choose a confirmed non-prescription configuration.
