I've had the OR Seattle Sombrero for about 15 years. It has seen me through dreary, drizzle in northern Minnesota's late spring when backpacking along the Superior Hiking Trail. It protected me admirably in Southeast Alaska during several rainy days in Juneau and elsewhere and it has been a great hat to wear when you don't want to carry an umbrella when walking about town. I've never had my head get wet when wearing this hat and it has been stuffed into pockets, crammed into backpacks and forgotten in the backseats of cars many times. One caveat: the brim is perfectly positioned in the back to funnel water away from your head. If you have a rain jacket with a hood, it takes a little thinking to position the hood in such a way that it doesn't function as a conduit to dump water inside your rain jacket--and down your back. Not a design flaw, but just something you need to remember before getting wet.
