With the power to block out the light so you're cool in the shade and safe from sunburns, umbrellas are essential additions to any alfresco ensemble. Take this one for example: designed to live outdoors, it is constructed from weather-resistant materials that don't mind UV light beaming down or rainstorms rolling through. This design is an easy fit for any deck or patio, pair it with a base to keep it anchored, or let it occupy the opening in your dining table.
