Good sun hat with low-to-moderate coverage and lightweight, fast-drying fabric that stays cool in hot temps. I use it for hiking and trail running in the summer, and expect to use it for ski touring this coming season. The lanyard keeps it on my head on the downhills. I gave it four stars because I don't think the Medium size parameters as listed on the website are very accurate; I got the Medium, which should fit, and it's a bit too tight. The interior velcro closure just kind of gets in the way and doesn't offer my any useful adjustability. Maybe something with some elasticity would be better.
