The sun is powerful here, and I love to hike in the mountains. This hat greatly mitigates the 'tingly scalp' feeling from uv penetrating my other hiking hats. The brim is wide, a real bonus, and it's 'crushable' as well. Only nick in an otherwise perfect score is the sizing; I have a larger-than-average head, so ordered the L-XL. Well, it's a bit big, but I'm hoping after a washing it'll fit better. But it is still usable as-is.
