The anti-headache guide: how to choose sunglasses compatible with your ultra gear

Cap, sunglasses, headlamp… in ultra trail running, stacking gear on your head can quickly become an issue.

Pressure on the temples, discomfort, headaches after a few hours — it's a common problem, and often misunderstood. And contrary to what many think, it's not just about fatigue.

In many cases, your gear setup is the real cause.

Why your sunglasses can cause headaches

In ultra distances, multiple elements overlap: sunglass arms, a cap or visor, and your headlamp strap. This stacking effect creates pressure points, especially around the temples.

Over time, this constant pressure can lead to:

  • Localized pain
  • A feeling of compression
  • Persistent headaches

The issue doesn't come from one piece of gear, but from how they all interact.

Why temple design makes all the difference

Not all sports sunglasses are designed to be worn with additional gear. Thick or rigid temples can create constant pressure under a cap or headlamp.

On the other hand, thinner, more flexible temples help distribute pressure more evenly and reduce contact points. The result: better long-distance comfort and fewer distractions.

  • Less pressure on the temples
  • Better stability while moving
  • Long-lasting comfort

Technologies like Thermogrip® also help maintain a secure fit without over-tightening.

Weight: the underestimated factor

Weight is often overlooked, especially on shorter runs. But in ultra, every detail matters.

Heavier sunglasses can:

  • Increase pressure on sensitive areas
  • Slip with sweat
  • Require constant readjustment

Those small adjustments add up, creating tension and fatigue over time.

Lighter frames, on the other hand, stay in place and feel almost unnoticeable — even after hours on the trail.

The goal is simple: reduce pressure points while maintaining a secure fit.

Look for:

  • Thin, flexible temples
  • A stable fit without excessive pressure
  • Lightweight frames
  • Compatibility with caps and headlamps

Take action

If you regularly experience headaches during your runs:

  • Test different gear setups

  • Adjust your equipment accordingly

Sometimes, switching to the right pair of sunglasses is all it takes to improve both comfort and performance over time.
