Great glasses for hiking
Having used these on a trek in the Sahara Desert, they did protect from the sun and sand well, but had a couple of issues.
Both my partner and I had pain above the ears, where these glasses pressed a bit too hard into our heads.
The other issue is the securing strap supplied. I connects to the glasses with plastic clips, but these are fitted with the sharp point inwards, and this does hurt after a while of wearing. The strap could also be longer.
We will use again, but not for extended periods, and will probably loose the retaining strap.
