Simms Women's Gore-Tex Sombrero - The GORE-TEX® membrane contains 9 billion microscopic pores per square inch. These pores are so small that water droplets cannot get through but water vapor can still escape. Water from the outside cannot penetrate and cold winds cannot pass through, but perspiration can escape easily, keeping you dry and comfortable all day.
