If 20 years as Outdoor Research's best-selling hat doesn't convince you that the Seattle Sombrero can keep you bone dry, nothing will. Backpacker Magazine's 2005 Editor's Choice Gold Award winner.

The foam-stiffened brim floats in case you drop your hat into an accommodating river or lake. Hook-and-loop tabs on brim and dome allow you to flip up the sides of the brim when the rain subsides.
