Sun Precautions has a drape style hat that works like a hat/buff, or hat/bandana, but with some advantages, imo. It's 100 spf (solumbra fabric). The drape hangs loose and so is probably cooler than a buff. It's great for mosquitoes, again partly because of the loose fit but also because of the fabric. It's highly adjustable with velcro attachments. You can leave it entirely loose or 'zip' it up to your chin or more, just above your nose, depending on your needs. I easily adjust it on the fly, even while using hiking poles, depending on mosquitoes or sun/shade/snow situations. In any case your ears and neck are always covered. Finally, it has a big forward brim.
Yeah it's dorky but no more so than a buff, perhaps.
This is my go-to hat in mosquito season, or while snowshoeing in sun. Otherwise, I wear a Sunday Afternoons wide brimmed hat.
I tried wearing a buff while nordic skiing but my glasses would always fog!
