        Comments about Eastern Mountain Sports EMS Thunderhead Cap:

        Bought this hat for the Inca Trail in Peru, couldn't be happier. We spent 3 days in the rain, allowed me to enjoy the world without a rain hood on all of the time.

        Most comfortable in temps less than 80 deg F, could get a little warm in the sun.
