Tested in some of the heartiest downpours the world has to offer, the Seattle Sombrero is a rainy day classic. A seam taped Taslan Gore-Tex® crown provides waterproof protection, while a soft, brushed tricot interior wicks moisture. The foam-stiffened brim directs water away from your head when it's gushing. Hook/loop tabs on brim and dome allows sides of brim to be flipped up when the weather is fair. In windy conditions a removable chin cord and an internal cinch-band adjustment keep this sombrero secure. One of the most popular and versatile hats around. For sizing, measure head circumference from center of forehead around fullest part of the head.
