About Outdoor Research Aquifer Sombrero

Outdoor Research Aquifer Sombrero
The Outdoor Research Aquifer Sombrero is ideal for your everyday outdoor strolls or trips. It is made from a 86% nylon, 14% polyester ripstop blend, lightweight, breathable, and wicks away moisture and sweat continuously, to give you a cool, dry head. A dark-colored Supplex nylon under the brim keeps the sun out of your eyes and reduces glares on those bright sunny days. The adjustable chinstrap keeps your hat firmly in place, so it does not blow off in a gust of wind. Its external drawcord lets you change the hat to your ideal fit. A foam-stiffened brim lets your hat float in water, if it ever falls into a puddle. It is also lightweight in design (3.1 oz.) and easy to carry along. Keep a cool head while you're outdoors with the Outdoor Research Aquifer Sombrero.

    Shopper  where is it of origin ?
    Alex S  This hat is made in China.
    David C  Is this hat easy to clean? Can you wash it in the washing machine? Or, do you hand wash it. Does it have a warranty?
    MARTIN L  Directions say handwash cold, no dry cleaning; although after my Amazon expedition, I will wash delicate cycle cool with non agitating washing machine and quite sure it will be just fine. As of warrany check with Columbia Sportswear Company.
