Common ALPINE trekking issues, solved

Exposed glare, rock-and-snow detail, strong wind and route checks place different demands above the treeline. Open each card to see the 2nu response.

01

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.

02

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.

03

Wind and long movement shift the frame

Strong wind, climbing movement and long wear can make a loose frame move, while over-tightening creates local pressure.

How 2nu solves it

FlexFoam™ + FlexLock™

Adjust a FlexFoam™ frame by hand first, then wear it for about five minutes. FlexLock™ distributes holding force around the head for stable wraparound support instead of relying on one tight pressure point.

04

Map, GPS and watch screens go dark

Some polarized lenses can make navigation and safety screens appear dark at certain angles.

How 2nu solves it

Hexachroma for route checks

Hexachroma helps reduce common screen blackout while keeping polarized glare control. Results still vary by device and angle, so test the route tools you rely on before a long trek.

Questions before you choose

Should I choose Hexachroma or TVO Pro for high mountain trekking?

Choose TVO Pro when strong polarized control of sustained snow, pale-rock and exposed-surface glare is the main priority. Choose flagship Hexachroma when you also want higher terrain detail and easier checks of maps, GPS, phone or watch screens.

Why 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.

Can polarized lenses darken map, GPS or watch screens at altitude?

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.

How 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.
