OK - so this is admittedly OCD for most, but for me (very pasty, having had to have one cancerous skin patch frozen off already), I hope it won't seem terribly unreasonable.

I plan on taking the standard - a nice sun hoodie with a baseball cap.

I went to the high Himalayas and did 3 Passes Trek - entirely sun exposed as high as 18.5k feet - and took the UV Coolnet Buff along with my cap and sun hoodie. Combining all that with sunscreen and sunglasses worked great for me.

What I found though is:

1. The buff makes it so hard to breathe huffing and puffing up climbs

2. Eventually, the buff "wetted out" from my breath such that it it became even harder for the air to get through

3. Even in the best cases, the moisture from my breath would often go up and out, fogging up my glasses and making it hard to see

4. The buff had a tendency to ride up into my eyes, or down so it no longer covered my face.

Has anyone figured out the perfect way to address all these things?

The only thing I've found that meets the breathability requirements is a vinyl coated mesh - and of course that would not work.

I think I might be relegated to adding earloops to my own buff and making a few cuts in the buff so as much of my breath can escape as possible.

Or I'd be tempted with this, but I imagine it would be hotter than blue blazes and a real problem when there is anything more than a tiny breeze.

But does anyone have a battle-tested piece of gear they could recommend instead?
