The Columbia Watertight II is an all-around perfect idea for a rain jacket. Built with Omni-Tech seam-sealed waterproof construction, the Watertight II not only keeps you dry, it's also breathable. So on humid days or when you perspire, vapor escapes to keep you comfortable instead of clammy. It also holds its own against the wind, too. All in a lightweight, packable design that's perfect for exploring.
