Woman wearing black 2nu Halo sunglasses with deep-blue lenses in high mountain light for the Driving and High Mountain Trekking sunglasses guide.

Your activity match

Drive in daylight to exposed high ground with screens, road glare, and snow reflection covered.

Low-angle sun and navigation lead into rock, snow, and long route checks above the treeline. Hexachroma supports dashboard, map, and terrain detail; TVO Pro prioritises strong polarized glare control. Daytime driving only.

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

Low sun and wet-road glare

Morning and late-afternoon sun, wet roads, glass and vehicle reflections can flatten road detail.

How 2nu solves it

Match the lens to daytime driving

Choose TVO Pro when polarized glare control is the priority. Choose Hexachroma when you also want clearer detail and a screen-friendlier polarized option. Both are daytime sunglasses; neither is intended for night driving.

02

Exposed snow and rock create hard glare

Above the treeline, direct sun and reflected light can remain intense for long sections with little natural shade.

How 2nu solves it

Start with ALPINE-rated glare control

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.

03

Screens that darken at an angle

Some polarized lenses can make navigation, dashboard or reversing displays look dark from certain angles.

How 2nu solves it

A screen-friendlier polarized option

Hexachroma helps reduce common screen black-out effects while retaining polarized glare control. Results vary by display, polarization direction and viewing angle, so test your usual screens while the vehicle is parked.

04

Rock, snow and shadow detail changes quickly

Terrain can move from bright snow or pale rock into deep shadow, making surface texture and route cues harder to separate.

How 2nu solves it

Keep terrain detail in the decision

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.

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 daytime driving?

Choose TVO Pro when polarized glare control is your main priority. Choose Hexachroma when you also value clearer detail and frequent screen checks. Both are daytime sunglasses and are not intended for night driving.

02Why start with deeper blue- or gold-mirror configurations for ALPINE conditions?

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.

03Will polarized lenses darken my navigation or dashboard 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 results cannot be identical on every screen. Test your usual displays while the vehicle is parked.

04How do I compare fit for wind, climbing movement and long wear?

Use the frame-coverage and head-fit information in each product callout. 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 relying on one tight pressure point.
