Seattle Sombrero™ The legendary soggy climate of the Pacific Northwest prompted us to develop this hat for use in a wide assortment of activities. It’s great for active wet-weather pursuits such as sea kayaking, backpacking in the rainforest, or swinging a polaski on a rainy trailwork project. The totally seam-sealed Gore-Tex fabric crown prevents entry of any external moisture while also minimizing the accumulation of perspiration. The Seattle Sombrero is so effective that it carries Gore’s “Guaranteed To Keep You Dry” certificationnot an easy test to pass. Many people find the hoods on their rain jackets to be uncomfortable, tough to hear through, and an impairment to vision. A Seattle Sombrero is a much more comfortable alternative.
